Check Digit Verification of cas no

The CAS Registry Mumber 120533-75-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,5,3 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 120533-75:
(8*1)+(7*2)+(6*0)+(5*5)+(4*3)+(3*3)+(2*7)+(1*5)=87
87 % 10 = 7
So 120533-75-7 is a valid CAS Registry Number.

ETHYL ESTERS OF 1,4-DIHYDROPYRIDINE-3,5-DICARBOTHIONIC ACIDS

Vigante, B. A.,Ozols, Ya. Ya.,Chekavichus, B. S.,Dubur, G. Ya.

, p. 1017 - 1023 (2007/10/02)

Methods for the synthesis of the esters of 1,4-dihydropyridine-3,5-dicarbothionic acids by the thionation of the carbonyl analogs with Lawesson's reagent are developed.The influence of the substituents at the nitrogen atom on the course of the thionation reaction is considered.The physicochemical characteristics of this series of substances are analyzed; their reactivity in the reactions of N-alkylation, oxidation, and anion formation is studied.
