Check Digit Verification of cas no

The CAS Registry Mumber 1219458-25-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,4,5 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1219458-25:
(9*1)+(8*2)+(7*1)+(6*9)+(5*4)+(4*5)+(3*8)+(2*2)+(1*5)=159
159 % 10 = 9
So 1219458-25-9 is a valid CAS Registry Number.

Na2S2O4: A versatile reagent for the one-pot synthesis of 2-aryl-1h-imidazo[4,5-c]pyridines from 4-amino-3- nitropyridine and aldehydes via reductive cyclization

Dubey,Chowdary,Ramesh,Reddy, P. V. V. Prasada

experimental part, p. 697 - 708 (2011/03/19)

A highly efficient and versatile method for the synthesis of 2-aryl-1H-imidazo[4,5-c]pyridines 3 was achieved in one step via reductive cyclization of 4-amino-3-nitro-pyridines 4 with aromatic aldehydes in the presence of Na2S2O
