1263296-03-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1263296-03-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,2,9 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1263296-03:
(9*1)+(8*2)+(7*6)+(6*3)+(5*2)+(4*9)+(3*6)+(2*0)+(1*3)=152
152 % 10 = 2
So 1263296-03-2 is a valid CAS Registry Number.

Selective acylation of 5-nitro- and 5-ethoxycarbonyl-4,6-diaryl-3,4- dihydropyrimidin-2(1H)-ones
Sedova,Shkurko
experimental part, p. 1695 - 1701 (2011/03/18)
The acetylation and chloroacetylation of 5-nitro- and 5-ethoxycarbonyl- substituted 4,6-diaryl-3,4-dihydropyrimidin-2(1H)-ones proceeds regioselectively at the N3 atom of the heterocycle whereas the acetylation of the 5-aryloxy-substituted anal
