are provided for convenience and customs purposes only, the written description of the scope of these investigations is dispositive.
Global regulatory organizations, including the United States Environmental Protection Agency and The ACT on the Registration and Evaluation of Chemicals regulatory body in Korea, require all new chemical substances manufactured or imported to be identified by a CAS Registry Number
Under the Reference Section, there are areas to conduct an advanced search by narrowing the choices according to a number of categories (author, CAS registry number
, Journal, Database, Language, Dates, etcetera).

20583-873) as a possible candidate that was consistent with all the data.
Data can be queried by chemical name, CAS Registry number
, organic chemical class, or species name (scientific and common) from laboratory and field data in either fresh or saltwater.
While we didn't find a simple way to limit the search to the word benzene by itself, the search could be done using the CAS registry number
