Check Digit Verification of cas no

The CAS Registry Mumber 1447605-55-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,7,6,0 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1447605-55:
(9*1)+(8*4)+(7*4)+(6*7)+(5*6)+(4*0)+(3*5)+(2*5)+(1*5)=171
171 % 10 = 1
So 1447605-55-1 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.
