Check Digit Verification of cas no

The CAS Registry Mumber 76216-35-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,2,1 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 76216-35:
(7*7)+(6*6)+(5*2)+(4*1)+(3*6)+(2*3)+(1*5)=128
128 % 10 = 8
So 76216-35-8 is a valid CAS Registry Number.

SYNTHESIS OF AZOXYBENZENE-SbCl5 COMPLEXES AND THEIR SELECTIVE ORTHO-WALLACH REARRANGEMENT

Yamamoto, Jiro,Nishigaki, Yukihiro,Umezu, Masahiro,Matsuura, Teruo

, p. 3177 - 3180 (2007/10/02)

When an equimolar solution of various azoxybenzenes and SbCl5 in carbon tetrachloride were mixed, a 1:1 complex immediately deposited as orange crystals in high yield.The thermal reaction of these complexes in inert solvents gives o-hydroxy-azobenzene selectively.On the contrary, other Lewis acids, such as TiCl4, AlCl3, FeCl3 and ZnBr2 failed to give an isolatable complex with azoxybenzene, and their direct thermal reaction with azoxybenzene resulted in deoxygenation to yield azobenzene as a main product.
