Check Digit Verification of cas no

The CAS Registry Mumber 1649438-40-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,9,4,3 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1649438-40:
(9*1)+(8*6)+(7*4)+(6*9)+(5*4)+(4*3)+(3*8)+(2*4)+(1*0)=203
203 % 10 = 3
So 1649438-40-3 is a valid CAS Registry Number.

Enaminones in heterocyclic syntheses: Part 4. A new one-step synthetic route to pyrrolo[3,4-b]pyridine and convenient syntheses of 1,4-dihydropyridines and 1,1′-(1,4-phenylene)bis(1,4-dihydropyridine)

Mashaly,El-Gogary,Kosbar

, p. 1078 - 1085 (2014/08/05)

Reactions of cyano olefins with (i) enamino imides afforded novel pyrrolo[3,4-b]pyridines; (ii) enamino esters afforded new 1,4-dihydropyridines; and (iii) bisenamino ester afforded new 1,1′-(1,4-phenylene)bis(1,4- dihydropyridine). The new derivatives are planned as suggested drug candidates.
