Check Digit Verification of cas no
The CAS Registry Mumber 153861-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,8,6 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 153861-63:
(8*1)+(7*5)+(6*3)+(5*8)+(4*6)+(3*1)+(2*6)+(1*3)=143
143 % 10 = 3
So 153861-63-3 is a valid CAS Registry Number.

Synthesis of 1,2,4-Triazolium Salts: Reaction of 1-Azo-2-azonia-allene Salts with Nitriles
Amer, A. M.
, p. 431 - 438 (1995)
Alkyl ketone hydrazones 1 are oxidized with tert-butylhypochlorite to give geminal chloro azo compounds 2.These react with SbCl5 to give 1-aza-2-azonia-allene salts 3 as reactive intermediates which are intercepted with nitriles to yield 3H-1,2,4-triazoli
