693-29-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 693-29-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 693-29:
(5*6)+(4*9)+(3*3)+(2*2)+(1*9)=88
88 % 10 = 8
So 693-29-8 is a valid CAS Registry Number.

Reaction of Electrochemically Generated Triphenylphosphine Radical Cation with Amides and Ureas

Ohmori, Hidenobu,Sakai, Kiyoshi,Nagai, Noriko,Mizuki, Yasuyuki,Masui, Masaichiro

, p. 373 - 376 (2007/10/02)

Constant-current electrolysis of triphenylphosphine in dichloromethane in the presence of primary amides and N,N'-disubstituted ureas resulted in the formation of nitriles and carbodiimides, respectively.Dehydrosulfurization of thiobenzamide and N,N'-dicyclohexylthiourea was also effected by electrlysis under the same conditions, but probably through mechanisms different from those of dehydration of the corresponding amide and urea.Keywords-constant-current electrolysis; triphenylphosphine; primary amide; N,N'-disubstituted urea; nitrile; carbodiimide
