Check Digit Verification of cas no

The CAS Registry Mumber 171974-62-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,9,7 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 171974-62:
(8*1)+(7*7)+(6*1)+(5*9)+(4*7)+(3*4)+(2*6)+(1*2)=162
162 % 10 = 2
So 171974-62-2 is a valid CAS Registry Number.

Electrolytic Oxidation of Ketones in Ammoniacal Methanol in the Presence of Catalytic Amounts of KI

Chiba, Toshiro,Sakagami, Hirotoshi,Murata, Miki,Okimoto, Mitsuhiro

, p. 6764 - 6770 (2007/10/03)

The indirect electrooxidation of ketones in ammoniacal methanol using iodide ion as a mediator afforded 2,2-dialkyl-2,5-dihydro-1H-imidazoles 3 via an oxidative cyclocoupling of ketimine intermediates formed from ketones and ammonia.The treatment of 3 with dilute HCl gave α-amino ketone hydrochlorides 4 and the parent ketones in good yields.A similar electrooxidation of 3 resulted in the formation of the corresponding 2H-imidazoles 6, which were hydrolyzed to α-diketones and the parent ketones.The same products 6 could also conveniently be obtained by chemical oxidation of 3 with aqueous NaOCl.
