90834-07-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90834-07-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,3 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90834-07:
(7*9)+(6*0)+(5*8)+(4*3)+(3*4)+(2*0)+(1*7)=134
134 % 10 = 4
So 90834-07-4 is a valid CAS Registry Number.

A mechanistic deviation in the Bischler indole synthesis
Sanchez-Viesca,Gomez,Berros, Martha
, p. 367 - 372 (2007/10/03)
When α-bromo-2,4,5-trimethoxybutyrophenone reacted with p-toluidine, the unexpected 3,5-dimethyl-2-(2,4,5-trimethoxybenzyl)indole was obtained. This mechanistic deviation was also observed with α -bromo-2,4,5-trimethoxyvalerophenone and α -bromo-2,4,5-tri
