Different CAS Registry Numbers [1] are used for each form of a substance. For example, something simple like alanine will have one CAS# for the D form, another for L, another for "unspecified" and a fourth one for racemic. There would be another four CAS#s for the hydrochloride, four for the (1:1) sulfate, four for the (2:1)sulfate, etc.
According to CAS, his visionary view of CAS' potential "led to expansion, modernization, and the forging of international alliances with other information organizations." [15] CAS was an early leader in the use of computer technology to organize and disseminate information. [16] The CAS Chemical Registry System was introduced in 1965.
Many of these database companies use the same name for their file format as they do for their database (including Copac, CSA, ISI, Medline, Ovid, PubMed, and SciFinder). For the ability to retrieve citations from the particular databases (rather than the file format), please refer to the database connectivity table that is below this table.

The series of directories leading to a particular file is known as a "path". [1] In the context of CAS, these traditional approaches are referred to as "location-addressed", as each file is represented by a list of one or more locations, the path and filename, on the physical storage.
Herb Baumeister’s macabre double life began to unravel in 1994 when his 13-year-old son found a human skull and a pile of bones in the woods of Fox Hollow Farm, his $1 million estate in ...
Based on that old value, they compute some new value. Then they try to swap in the new value using CAS, where the comparison checks for the location still being equal to the old value. If CAS indicates that the attempt has failed, it has to be repeated from the beginning: the location is re-read, a new value is re-computed and the CAS is tried ...
