Check Digit Verification of cas no

The CAS Registry Mumber 203940-75-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,9,4 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 203940-75:
(8*2)+(7*0)+(6*3)+(5*9)+(4*4)+(3*0)+(2*7)+(1*5)=114
114 % 10 = 4
So 203940-75-4 is a valid CAS Registry Number.

A detailed investigation of the preparation of 2,7-diaminosuberic acid and 2,5-diaminoadipic acid derivatives using Kolbe electrolysis

Hiebl, Johann,Blanka, Michael,Guttman, Andras,Kollmann, Hermann,Leitner, Kornelia,Mayrhofer, Guenter,Rovenszky, Franz,Winkler, Karin

, p. 2059 - 2074 (2007/10/03)

The yield of protected 2,7-diaminosuberic acid (DAS) prepared by Kolbe reaction of N-protected α-glutamic acid esters is dependent on solvent, temperature, concentration of carboxylate onion, and protecting groups. The highest yield of protected L,L-2,7-diaminosuberic acid is obtained with Boc-Glu-OMe as starting material using MeOH/pyridine/NaOMe as electrolyte.
