CAS Headquarters Complex, completed in 1965 with addition (on left) in 1973. Columbus, Ohio. Chemical Abstracts (CA) began as a volunteer effort and developed from there. The use of volunteer abstractors was phased out in 1994. Chemical Abstracts has been associated with the American Chemical Society in one way or another since 1907. [13]

A CAS Registry Number [1] (also referred to as CAS RN [2] or informally CAS Number) is a unique identification number, assigned by the Chemical Abstracts Service (CAS) in the US to every chemical substance described in the open scientific literature, in order to index the substance in the CAS Registry.

Large databases, such as PubChem [11] [20] and ChemSpider, [21] have graphical interfaces for search. The Chemical Abstracts Service provides tools to search the chemical literature and Reaxys supplied by Elsevier covers both chemicals and reaction information, including that originally held in the Beilstein database.

Scopus provides chemical search by CAS number and by chemical name, while WoS does not have these features. On the other hand, WoS has chemical structure search, but only a small number of publications are actually indexed for chemical structure searches. SciFinder is the preferred option for chemical searches is all cases.
This is a list of CAS numbers by chemical formulas and chemical compounds, indexed by formula.The CAS number is a unique number applied to a specific chemical by the Chemical Abstracts Service (CAS).This list complements alternative listings to be found at list of inorganic compounds and glossary of chemical formulae
In 1907, the American Chemical Society set up the Chemical Abstracts Service (CAS). This weekly subscription service included a printed publication with summaries of articles in thousands of scholarly journals and claims in worldwide patents. This had a chemical substance index that, in principle, allowed searching by chemical name or formula. [38]
