Check Digit Verification of cas no

The CAS Registry Mumber 120623-59-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,6,2 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120623-59:
(8*1)+(7*2)+(6*0)+(5*6)+(4*2)+(3*3)+(2*5)+(1*9)=88
88 % 10 = 8
So 120623-59-8 is a valid CAS Registry Number.

2-(Methylpyridyl)-X-azolopyridines: Bases, Salts and Polymethine Dyes

Savarino, Piero,Carpignano, Rosarina,Viscardi, Guido,Barni, Ermanno,Di Modica, Gaetano

, p. 1675 - 1680 (2007/10/02)

A series of heterocyclic bases containing 2-(methyl-3-pyridyl)-X-azolo-pyridine was synthesized and the obtained bases were then quaternized.The structure of the salts were assessed by nmr and uv spectroscopy.From quaternary salts, styryl dyes were prepared and similarly characterized.The physical and spectroscopic data of the compounds were compared with those of the other isomers, previously described, and of the corresponding benzo-X-azole derivatives.
