74693-44-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74693-44-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,9 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74693-44:
(7*7)+(6*4)+(5*6)+(4*9)+(3*3)+(2*4)+(1*4)=160
160 % 10 = 0
So 74693-44-0 is a valid CAS Registry Number.

A convenient Synthesis of New Indole Derivatives
Saleha, Sabiha,Siddiqui, Amin A.,Khan, Nassem H.
, p. 81 - 82 (2007/10/02)
Several indole derivatives (IIa-g) have been prepared by refluxing equimolar amounts of the appropriate indole and 2,4-dinitrobenzoyl chloride, p-bromoaniline, isobutyl chloroformate and N-bromosuccinimide in ethanol in the presence of sodium acetate.
