Check Digit Verification of cas no

The CAS Registry Mumber 1421313-36-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,3,1 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1421313-36:
(9*1)+(8*4)+(7*2)+(6*1)+(5*3)+(4*1)+(3*3)+(2*3)+(1*6)=101
101 % 10 = 1
So 1421313-36-1 is a valid CAS Registry Number.

Chemical synthesis and characterization of epicatechin glucuronides and sulfates: Bioanalytical standards for epicatechin metabolite identification

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

, p. 157 - 169 (2013/06/05)

The monoglucuronides and sulfates of epicatechin, 3′- Omethylepicatechin, and 4′-O-methylepicatechin, respectively, were synthesized as authentic bioanalytical standards. Reversed-phase HPLC methods capable of baseline separation of the glucuronides and sulfates have been developed. Both the epicatechin glucuronides and sulfates were stable in the solid state when stored under ambient conditions and in aqueous solution when stored refrigerated. These results should prove invaluable to the research community as analytical standards as well as in future studies of the biological and pharmacological effects of epicatechin in humans.
