Check Digit Verification of cas no
The CAS Registry Mumber 65002-62-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,0,0 and 2 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 65002-62:
(7*6)+(6*5)+(5*0)+(4*0)+(3*2)+(2*6)+(1*2)=92
92 % 10 = 2
So 65002-62-2 is a valid CAS Registry Number.

TRANSESTERIFICATION PROCESS USING MIXED SALT ACETYLACETONATES CATALYSTS
-
Paragraph 0085-0087, (2013/04/13)
This invention is directed to a general catalyst of high activity and selectivity for the production of a variety of esters, particularly acrylate and methacrylate-based esters, by a transesterification reaction. This objective is achieved by reaction of an ester of a carboxylic or a carbonic acid, in particular of a saturated or unsaturated, typically, a 3 to 4 carbon atom carboxylic acid; with an alcohol in the presence of a catalyst comprising the combination of a metal 1,3-dicarbonyl complex (pref. Zn or Fe acetylacetonate) and a salt, in particular an inorganic salt, pref. ZnCl2, LiCI, NaCI, NH4CI or Lil. These catalysts are prepared from readily available starting materials within the reaction medium without the need for isolation (in-situ preparation).
