Check Digit Verification of cas no

The CAS Registry Mumber 70625-87-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,6,2 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 70625-87:
(7*7)+(6*0)+(5*6)+(4*2)+(3*5)+(2*8)+(1*7)=125
125 % 10 = 5
So 70625-87-5 is a valid CAS Registry Number.

Oxidative Cleavage Reaction of 3-Substituted Indoles Catalyzed by CuCl-Pyridine Complex under Oxygen

Tsuji, Jiro,Kezuka, Hiroaki,Takayanagi, Hiroshi,Yamamoto, Keiji

, p. 2369 - 2373 (1981)

Oxidative cleavage of 3-methylindole using a catalytic amount of copper (II) salts with added pyridine under an oxygen atmosphere was studied.Smooth cleavage of 3-methylindole took place to give 2-formamidoacetophenone in 73-80percent yield, whereas exclusive formation of a hydrate compound derived from 3,3'-dimethyl-3,3'-bi-3H-indole resulted under anaerobic conditions.Clean oxidative cleavage of N-acetyltryptamine, methyl 3-indolylacetate, and methyl 2-acetamido-3-(3-indolyl)propionate was also achieved, constituting a mimic of tryptophan-2,3-dioxygenase.
