	CAS registry number - Wikipedia, the free encyclopedia
		CAS registry numbers are unique numerical identifiers for chemical compounds, polymers, biological sequences, mixtures and alloys.
		Chemical Abstracts Service (CAS), a division of the American Chemical Society, assigns these identifiers to every chemical that has been described in the literature.
		For instance, to search for information about cocaine (CAS 50-36-2), one should include cocaine hydrochloride (CAS 53-21-4), since that is the most common form of cocaine when used as a drug.

	Chemical Abstracts Service - Wikipedia, the free encyclopedia
		Chemical Abstracts Service (CAS) is a division of the American Chemical Society which produces the Chemical Abstracts, an index of the scientific literature in chemistry and related fields.
		CAS also maintains the CAS registry, a comprehensive database of chemical substances.
		Each substance in this database receives a CAS registry number, and these numbers are now commonly used to uniquely identify chemical substances.

	Chemical Abstracts Service Annual Report to NSF
		The Chemical Society has now reported on the first year of what originally was to be a two-year program costing the taxpayers over $2 million.
		This does not mean that the benefits of a chemical registry and structure searching system will not ultimately benefit thousands of chemists throughout the world, in the same way that mankind may benefit from a hundred million dollar particle accelerator even though only a few may use it.
		Having planned on the encoding of 200,000 chemical compounds, the project has done closer to 800,000 and appears to be headed, in the already signed follow-up contract, toward at least doubling that figure.

	18 Millionth Chemical Substance Entered In World's Largest Database Of ChemicalInformation
		Chemical Abstracts Service reviews and summarizes chemistry research in patents, conference proceedings and more than 8,000 scientific journals; in the process, CAS scientists identify new chemical substances mentioned in new scholarly reports, and capture them in the CAS Registry file.
		New chemical substances are added to the CAS Registry at the rate of approximately one new record every 9 seconds.
		Chemical Abstracts Service is a division of the American Chemical Society, the world's largest scientific society, with a membership of more than 155,000 chemists and chemical engineers.

	Database Description
		Chemical substances are represented by CAS Registry Numbers, unique numbers assigned to each specific chemical compound.
		A record is a CA abstract number and any or all of its associated CAS data in bibliographic databases or a CAS Registry Number and any or all of its associated CAS data in substance databases.
		You may include information from CAS services for use in a critical review, presentation, or published work, where the sole purpose of such inclusion is to explain the use of CAS services.

	[No title]
		Any abstracting or indexing service which publishes its entries in a classified system is faced with a dilemma--where to put the main entry for an item which is clearly interdisciplinary.
		Since the beginning of 1972, publications on chemical history, education, and documentation (information science) have been abstracted primarily in section 20 of Chemical Abstracts.1 Some cross-references at the end of that section are given for relevant entries placed in other sections of CA.
		Chemical Abstracts is, after all, an abstracting journal which is devoted more to areas central to the discipline of chemistry than to supportive areas like chemical information science.

	Appeal of P.S. Docket No. 3/59 -- AMERICAN CHEMICAL SOCIETY
		The American Chemical Society is a non-profit scientific and educational membership corporation, organized and existing by an Act of Congress, P.L. 358, 75th Congress, 1st Session, 50 Stat.
		All of the revenue of the American Chemical Society is obtained from membership dues, subscriptions to its numerous journal and abstract publications, sale of advertising in these publications, and from cost-type contracts with the Government and other organizations.
		The decision in American Chemical Society, P.O.D. Docket No. 3/90, cited by petitioner as support for this argument, distinguishes, on the basis of the amount of editorial effort applied thereto, certain other indexes not directly involved in that proceeding from the publication which was the subject thereof.

		Arrangement of Abstracts in Print CA For ease of browsing, abstracts are grouped by subject area.
		From 1933-1966, each page had two columns of abstracts which were numbered, with letters running down the center of the page to identify where on the page the abstract fell.
		For other common chemicals, even if you can't find the specific chemical you want, you may be able to find a similar one and get a clue to follow.

		Chemicals in combinations of two or more can create a synergy, making the toxicity significantly higher than any of the individual chemicals.
		Other factors that need to be considered along with the combinations of chemicals are environmental conditions such as: humidity, light, temperature, the individual's body, and all the rest of the world surrounding all of us.
		Needless to say, there is no government or combination of governments that is capable of checking just the possible combinations of chemicals, let alone all possible variables.
