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.
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.
Reaxys is a web-based tool for the retrieval of information about chemical compounds and data from published literature, including journals and patents. The information includes chemical compounds, chemical reactions, chemical properties, related bibliographic data, substance data with synthesis planning information, as well as experimental procedures from selected journals and patents.
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.
It has since been adopted for use as a tool in the genetic engineering of higher organisms. Designing an appropriate gRNA is an important element of genome editing with the CRISPR/Cas system. A gRNA can and at times does have unintended interactions ("off-targets") with other locations of the genome of interest.
CPMP-Tools is a free open-source software-package for Computer Algebra System (CAS). CPMP is an abbreviation for Core-Plus Mathematics Project. CPMP-Tools is released under the GNU General Public License. [1] It works with three operating systems. CPMP-Tools is made for teaching mathematics at the high school level. [2] [3]
