Check Digit Verification of cas no

The CAS Registry Mumber 112616-26-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,6,1 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 112616-26:
(8*1)+(7*1)+(6*2)+(5*6)+(4*1)+(3*6)+(2*2)+(1*6)=89
89 % 10 = 9
So 112616-26-9 is a valid CAS Registry Number.

The Reaction of Malononitrile with Some Enamines of 1-Indanone. Synthesis of o-Aminonitriles of Indenopyridine and Indenothiopyran

Bogdanowicz-Szwed, Krystyna,Feret, Hanna,Lipowska, Malgorzata

, p. 623 - 627 (2007/10/02)

The reaction of enamines of 1-oxo-indan-2-carboxylic acid anilides (1) with malononitrile yielded 2-arylcarbamylindenylidene-malononitriles (3), which in alkaline solution underwent cyclization to indenopyridines (4).Enamines of 1-oxo-indan-2-carbothionic acid anilides (2) reacted with malononitrile yielding indenothiopyrans (6), which under influence of alkalis were transformed to indenopyridines (8). - Enamines of β-Ketoacid Anilides, o-Aminonitriles, Indenopyridine, Indenothiopyran
