Check Digit Verification of cas no

The CAS Registry Mumber 402573-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,2,5,7 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 402573-75:
(8*4)+(7*0)+(6*2)+(5*5)+(4*7)+(3*3)+(2*7)+(1*5)=125
125 % 10 = 5
So 402573-75-5 is a valid CAS Registry Number.

Enantioselective synthesis of orthogonally protected (2R,3R)-(-)- epicatechin derivatives, key intermediates in the de novo chemical synthesis of (-)-epicatechin glucuronides and sulfates

Zhang, Mingbao,Erik Jagdmann Jr.,Van Zandt, Michael,Beckett, Paul,Schroeter, Hagen

, p. 362 - 373 (2013/06/27)

Ten orthogonally protected (-)-epicatechin and 3′- or 4′-O-methyl-(-)-epicatechin derivatives were prepared in a regiospecific and enantioselective manner. For each orthogonally protected (-)-epicatechin derivative, one specific phenolic hydroxyl was protected with a methoxymethyl (MOM) or p-methoxybenyzl (PMB) group and the remainder were protected as benzyl ethers. These uniquely protected (-)-epicatechin derivatives were designed to facilitate the regiospecific installation of a glucuronic acid or sulfate unit onto (-)-epicatechin after selective removal of the MOM or PMB protecting group to provide authentic standards of (-)-epicatechin glucuronides and sulfates.
