25083-12-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25083-12-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,0,8 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 25083-12:
(7*2)+(6*5)+(5*0)+(4*8)+(3*3)+(2*1)+(1*2)=89
89 % 10 = 9
So 25083-12-9 is a valid CAS Registry Number.

Mannich Bases of 9-Phenyl-1,2,3,4-tetrahydrocarbazole
Viswanathan, N.,Gokhale, Uday B.
, p. 121 - 124 (2007/10/02)
Several Mannich bases (5-9) have been prepared from 9-phenyltetrahydrocarbazole (3).The site of the Mannich reaction has been proved to be C-1 by Hofmann degradation and subsequent reduction to yield 11.Compounds (5) and (7) are reduced by sodium and ammo
