Check Digit Verification of cas no

The CAS Registry Mumber 81635-61-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,3 and 5 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81635-61:
(7*8)+(6*1)+(5*6)+(4*3)+(3*5)+(2*6)+(1*1)=132
132 % 10 = 2
So 81635-61-2 is a valid CAS Registry Number.

Esters of 1,4-dihydropyridine-3- and -3,5-carbothiolic acids

, p. 170 - 178 (2007/10/02)

Methods for the preparation of esters of 1,4-dihydropyridine-3- and -3,5-carbothiolic acids were developed, and their structure and reactivity were studied. A comparative analysis was made of the spectroscopic characteristics of sulfur-containing esters of the 1,4-dihydropyridine series and their oxygen analogs. More strongly expressed electron-acceptor properties of the COSAlk groupings as compared with alkoxycarbonyl substituents were observed.
