Chemical formula Synonyms CAS number C 10 H 16 N 2 O 8: Ethylenediaminetetraacetic acid (EDTA): 6381–92–6 C 12 H 22 O 11: sucrose: 57–50–1 C 18 H 29 O 3 S: sodium dodecyl benzenesulfonate: 2155–30–0
The latter process provides a high-yield route to 1,1-binaphthol: [22] Such compounds are intermediates in the synthesis of BINAP and its derivatives. [20] Copper(II) chloride dihydrate promotes the hydrolysis of acetonides, i.e., for deprotection to regenerate diols [23] or aminoalcohols, as in this example (where TBDPS = tert ...
The check digit is found by taking the last digit times 1, the preceding digit times 2, the preceding digit times 3 etc., adding all these up and computing the sum modulo 10. For example, the CAS number of water is 7732-18-5: the checksum 5 is calculated as (8×1 + 1×2 + 2×3 + 3×4 + 7×5 + 7×6) = 105; 105 mod 10 = 5.
List of CAS numbers by chemical compound_(Inorganic), Otherwise it confuses readers--124.78.215.110 12:18, 2 May 2009 (UTC) I believe that this article has to be splitted with many in the future, as the collection of CA substance book has not got one but heaps

This is a list of Superfund sites in Texas designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

CAS Number. 7758-89-6 ... Early investigators observed that copper(I) halides catalyse 1,4-addition of Grignard reagents to alpha,beta-unsaturated ketones ...
In 2021, CAS rebranded along with a change in logo. The organization updated their mission to be more focused on dynamic responsiveness due to ongoing changes within scientific industries and communities. [19] In 2022, CAS announced the release of almost half a million CAS registry numbers under an open license in their Common Chemistry project.
