Check Digit Verification of cas no

The CAS Registry Mumber 117608-96-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,0 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 117608-96:
(8*1)+(7*1)+(6*7)+(5*6)+(4*0)+(3*8)+(2*9)+(1*6)=135
135 % 10 = 5
So 117608-96-5 is a valid CAS Registry Number.

The Chemistry of Polycyclic Arene Imines. VII. Reaction of Phenanthrene 9,10-Imine with Aromatic Carboxaldehydes, Carboxylic Acids and Acetylenic Esters

Shtelzer, Sarah,Sheradsky, Tuvia,Blum, Jochanan

, p. 1581 - 1585 (2007/10/02)

The reactions of phenanthrene 9,10-imine (1) with aromatic aldehydes, benzoic acids and acetylenedicarboxylic esters were invetigated.The aldehydes were shown to give 1--1a,9b-dihydrophenanthroazirine 2.The 'dimeric' structure of these products was established by X-ray diffraction analysis.The carboxylic acids proved to form in the presence of dicyclohexylcarbodiimide, N-aroylphenanthrene 9,10-imines 7, that readily undergo rearrangement to N-aroyl-9-phenanthrenamines 8.Esters of acetylenedicarboxylic acid gavethe corresponding esters of (Z)-2-(1a,9b-dihydrophenanthroazirine-1-yl)-2-butendioic acid 10.
