Check Digit Verification of cas no

The CAS Registry Mumber 82756-11-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,7,5 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 82756-11:
(7*8)+(6*2)+(5*7)+(4*5)+(3*6)+(2*1)+(1*1)=144
144 % 10 = 4
So 82756-11-4 is a valid CAS Registry Number.

Reactions of 6-Methyl- and 4,6-Dimethyl-2-arylaminonicotinonitriles with Acids

Shramm, N. I.,Konshin, M. E.

, p. 511 - 514 (2007/10/02)

A substituted nicotinic acid is formed when 6-methyl-2-anilinonicotinonitrile is refluxed with concentrated hydrochloric acid, whereas 4,6-dimethyl-2-anilinonicotinonitrile is not hydrolyzed under these and more severe conditions because of steric hindrance.Both of these nitriles undergo cyclization to 10-aminobenzo-1,8-naphthyridine derivatives under the influence of concentrated sulfuric acid.When 6-methyl-2-arylaminonicotinonitriles are heated in polyphosphoric acid (PPA), they are converted to 2-arylaminonicotinic acid amides and, in part, to benzo-1,8-naphthyrid-10-one derivatives, while 4,6-dimethyl-2-arylaminonicotinonitriles are converted primarily to 10-aminobenzo-1,8-naphthyridines.
