However, no experimental genotoxicity data could be obtained from the ECHA database for three of these, since they were registered for intermediate use only (CAS number
75-55-8 and 96-23-1) or the information was limited to read-across data (CAS number

(3) CAS number
: A unique identifying number for every chemical substance assigned by the CAS Registry System, which is operated and administered by the Chemical Abstracts Service.
It consists of approximately 10,000 compounds listed h Chemical Abstracts (CAS) registry number where known, or the common chemical name or trade name where the CAS number
is not available.

Three cross-indices are provided as appendices to permit rapid location of a material by CAS number
, synonym, or DOT guide number.
The CAS number
and chemical structure analysis of Varox DCBP-50 paste is CAS #133-14-2; EINECS/ELINCS No.
Most of the laboratory exercises include: background, reading assessment, objective, principle of method, chemical with CAS number
and hazards, reagents, precautions and waste disposal, supplies, equipment, procedure, data and calculations, questions and references.
"The new CAS number
search function reduces the ambiguity of search results for the global chemical industry," said Julie Mason, general manager of Kellysearch.com.
Additional MSDS Manager features allow users to: simplify the MSDS process with a powerful search engine to search for MSDSs by location (site, storage areas, and sub areas), material name, synonyms, components, CAS number
, MSDS status, and vendor all from one web form; streamline their ability to comply with the OSHA Hazard Communication Standard; empower employees to access electronic MSDS information via the Internet; know the status of all of their MSDSs, including current (active), inactive, pending and discontinued documents and data; reduce hazardous material Right-To-Know compliance costs and non-compliance risks.
