    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 ...

    Screenshot of the CAS Common Chemistry database with information about caffeine ().. A CAS Registry Number [1] (also referred to as CAS RN [2] or informally CAS Number) is a unique identification number, assigned by the Chemical Abstracts Service (CAS) in the US to every chemical substance described in the open scientific literature, in order to index the substance in the CAS Registry.

    But these websites aren't the most prominent ones for CAS # databases, like Pubchem, etc. so these will be added. --Mkcas 17:28, 26 May 2010 (UTC) Found a couple more relevant chemical databases that might be helpful. Added to bottom of the list. Seem to be better than some of the links already there, and no spammy ads on them.

    Different CAS Registry Numbers [1] are used for each form of a substance. 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.
