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.
An lock-free deque using hazard pointers and requiring only DWCAS rather than full DCAS was proposed by Maged Michael in 2003. [4] In general however, DCAS is not a silver bullet : implementing lock-free and wait-free algorithms using it is typically just as complex and error-prone as for CAS.

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. It is very important that we match the correct form CAS# to our Chemboxes!
How to use hand sanitizer properly. If you’re on the go or nowhere near soap and water, doctors say that hand sanitizer is a helpful option. It’s important to use products that contain 60% ...
The usual place to download a molecular structure file is the PDB website, www.pdb.org, which allows you to search based on a four-character PDB ID or based on keyword descriptions of a particular structure. Once you have found the structure you're looking for, click the 'download files' link on the left side of the page, then click the first ...
Screenshot of the CAS Common Chemistry database with information about caffeine ().. 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.
