87591-76-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87591-76-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,9 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 87591-76:
(7*8)+(6*7)+(5*5)+(4*9)+(3*1)+(2*7)+(1*6)=182
182 % 10 = 2
So 87591-76-2 is a valid CAS Registry Number.

Synthesis of some substituted pyrido[1,2-a]pyrimidin-4-ones and 1,8-naphthyridines
Ferrarini,Mori,Livi,et al.
, p. 1053 - 1057 (1983)
The substituted 4H-pyrido[1,2-a]pyrimidin-4-ones (I) were obtained by the condensation of substituted 2-aminopyridines with β-ketocarboxylic esters in PPA. Some of the derivatives I were transformed into the corresponding 1,8-naphthyridines II and III.
