Check Digit Verification of cas no

The CAS Registry Mumber 243977-32-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,3,9,7 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 243977-32:
(8*2)+(7*4)+(6*3)+(5*9)+(4*7)+(3*7)+(2*3)+(1*2)=164
164 % 10 = 4
So 243977-32-4 is a valid CAS Registry Number.

Derivatives of condensed thienopyrimidines 12. Synthesis of substituted pyrano(thiopyrano)-[4′,3′:4,5]thieno[2,3-d]pyrimidines

Oganisyan,Noravyan

, p. 1181 - 1184 (1998)

A method for the synthesis of new condensed derivatives of 4-oxo-2-thioxo-5,6-dihydro-8H-pyrano(thiopyrano)[4′,3′:4.5]thieno[2, 3-d]pyrimidines has been developed. It has been established that with increasing electron acceptor ability of the substituents
