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!
CAS, a division of the American Chemical Society, is pleased to announce that it will contribute to the Wikipedia project. CAS will work with Wikipedia to help provide accurate CAS Registry Numbers ® for current substances listed in Wikiprojects-Chemicals section of the Wikipedia Chemistry Portal that are of widespread general public interest.
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.
I checked PubChem, which is a good source for those like me who don't have direct SciFinder access. It has lolamicin as CAS 2930690-12-1 but none of the others. Mike Turnbull 11:48, 4 December 2024 (UTC) I added the CAS numbers for all but CDD-2807 which doesn't currently have an assigned CAS number.

The Alzheimer's Association released a list of gift recommendations for individuals with the disease at every stage of dementia. Experts offer insights on how to navigate the holiday amid dementia.
The original paper that described the CANGEN [2] algorithm claimed to generate unique SMILES strings for graphs representing molecules, but the algorithm fails for a number of simple cases (e.g. cuneane, 1,2-dicyclopropylethane) and cannot be considered a correct method for representing a graph canonically.

The WikiProject: Molecular and Cellular Biology supports the use of PyMOL, an open-source molecular visualization program, for the creation of images of biomolecules such as proteins, DNA, and related complexes. This page provides introduces the software and demonstrates how to create high-quality images of proteins.
