1449431-72-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1449431-72-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,9,4,3 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1449431-72:
(9*1)+(8*4)+(7*4)+(6*9)+(5*4)+(4*3)+(3*1)+(2*7)+(1*2)=174
174 % 10 = 4
So 1449431-72-4 is a valid CAS Registry Number.

Synthesis and biological evaluation of some new pyrimidine derivatives
El-Mahdy, Kamelia M.,El-Kazak, Azza M.
, p. 841 - 851 (2013/05/08)
Reaction of 2-mercaptopyrimidine 1 with ethyl chloroacetate afforded isomeric pyrimidines 2 and 3. Interaction of 3 with bifunctional nitrogen nucleophiles yielded pyrimidotriazine 5 and 7. Hydrazinolysis of 2 by hydrazine hydrate afforded hydrazinopyrimi
