Check Digit Verification of cas no

The CAS Registry Mumber 249526-05-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,9,5,2 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 249526-05:
(8*2)+(7*4)+(6*9)+(5*5)+(4*2)+(3*6)+(2*0)+(1*5)=154
154 % 10 = 4
So 249526-05-4 is a valid CAS Registry Number.

Synthesis and reactions of 4,6-disubstituted pyrimidin-2(1H)-thione derivatives as antimicrobial agents

El-Hashash,Abdel-Rahman,Soliman

, p. 87 - 92 (2007/10/03)

Pyrimidines containing other heterocyclic moieties are known to exhibit varied biological and pharmacological properties1-5. In view of these observations, the present work describes the synthesis of some new substituted pyrimidinthiones starting from α1 B-unsaturated carbonyl compounds and their antimicrobial activities. An attempt is made to study the structure activity relationship.
