Check Digit Verification of cas no

The CAS Registry Mumber 256530-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,5,3 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 256530-63:
(8*2)+(7*5)+(6*6)+(5*5)+(4*3)+(3*0)+(2*6)+(1*3)=139
139 % 10 = 9
So 256530-63-9 is a valid CAS Registry Number.

Five-ring analogs of nifedipine. 3. Synthesis and reactions of 1,4-dihydropyridines with 4-(4-nitro-5-imidazolyl)-substituents

Goerlitzer,Klanck

, p. 814 - 819 (2007/10/03)

In the Hantzsch pyridine synthesis the 4-nitro-5-imidazolylcarbaldehydes 4 react with methyl 3-aminocrotonate or 3-aminocrotononitrile in acetic acid to yield the 1,4-dihydropyridines (DHP) 5 and 6. The corresponding pyridines 7 and 8 are obtained by oxid
