74731-86-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74731-86-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,3 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74731-86:
(7*7)+(6*4)+(5*7)+(4*3)+(3*1)+(2*8)+(1*6)=145
145 % 10 = 5
So 74731-86-5 is a valid CAS Registry Number.

INSERTION OF 1,3-DITHIOLIUM CARBENES INTO N-H BOND OF AMIDES AND IMIDES
Buza, Daniela,Gradowska, Wanda
, p. 1059 - 1069 (2007/10/02)
It was found that 1,3-dithiolium carbenes (4a-d) generated from 2-methoxy-1,3-dithioles (1a-d) were inserted into N-H bond of N-methylbenzamide, acetanilide and succinimide to form N-(1,3-dithiol-2-yl)amides (imides) 8-10, respectively.It was shown that N
