Check Digit Verification of cas no

The CAS Registry Mumber 91559-95-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,5 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91559-95:
(7*9)+(6*1)+(5*5)+(4*5)+(3*9)+(2*9)+(1*5)=164
164 % 10 = 4
So 91559-95-4 is a valid CAS Registry Number.

Arylimidodimagnesium Reagents. X. The Mild Reagent Derived from 2-Aminopyridine and Formation of Highly Reactive Azoxypyridines in the Reaction with Nitrobenzenes

Okubo, Masao,Sugimori, Chieko,Tokisada, Mitsunao,Tsutsumi, Toshiki

, p. 1644 - 1646 (1986)

The reaction of iminodimagnesium reagent derived from 2-amino-4-methylpyridine with nitrobenzenes was examined.The relative yields of the azoxypyridine formed via condensation and the azopyridines via deoxygenation and oxidative dimerization were explained in terms of weak electron-accepting ability of the azoxypyridine.
