142138-63-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142138-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,1,3 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142138-63:
(8*1)+(7*4)+(6*2)+(5*1)+(4*3)+(3*8)+(2*6)+(1*3)=104
104 % 10 = 4
So 142138-63-4 is a valid CAS Registry Number.

SYNTHESIS AND ALKYLATION OF AMIDINES OF THE PHENANTHRIDINE SERIES
Mikhailovskii, A. G.,Bakrin, M. I.
, p. 1091 - 1094 (2007/10/02)
A number of 6-aminophenanthridines have been synthesized; upon alkylation, these compounds form amidinium salts.Depending on the structure of the original amidine, the alkylation may proceed at the exocyclic (N-alkyl), phenanthridine (N-aryl), or pyridine
