Check Digit Verification of cas no

The CAS Registry Mumber 309277-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,2,7 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 309277-28:
(8*3)+(7*0)+(6*9)+(5*2)+(4*7)+(3*7)+(2*2)+(1*8)=149
149 % 10 = 9
So 309277-28-9 is a valid CAS Registry Number.

Reactions of cyclic enaminoketones with benzylidenemalononitriles. Synthesis of new fused heterocyclic systems containing the 1,4-dihydropyridine fragment

Lichitsky,Ivanov,Dudinov,Woznesensky,Krayushkin

, p. 2428 - 2432 (2007/10/03)

The reactions of cyclic cnaminoketones with benzylidenemalononitriles were examined and a new procedure was developed for the synthesis of fused heterocyclic systems containing the 1,4-dihydropyridine ring, viz., thienopyrimidoquinolines and furopyrimidoq
