Check Digit Verification of cas no

The CAS Registry Mumber 99762-60-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,6 and 2 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99762-60:
(7*9)+(6*9)+(5*7)+(4*6)+(3*2)+(2*6)+(1*0)=194
194 % 10 = 4
So 99762-60-4 is a valid CAS Registry Number.

Synthesis of condensed derivatives of 2-substituted thieno[2,3-d]pyrimidin-4-ones

Kazaryan,Noravyan,Gevorkyan

, p. 825 - 828 (2007/10/03)

A preparative method of synthesis of 2-substituted thieno[2,3-d]pyrimidin-4-ones involving deamination of the corresponding 3-amino derivatives by sodium nitrite in acidic medium is proposed. A possible reaction mechanism is considered. 1999 KluwerAcademic/Plenum Publishers.
