83871-62-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83871-62-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,8,7 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 83871-62:
(7*8)+(6*3)+(5*8)+(4*7)+(3*1)+(2*6)+(1*2)=159
159 % 10 = 9
So 83871-62-9 is a valid CAS Registry Number.

, p. 131 - 135 (2002)
The treatment of N-benzylideneaniline (1a) with a half-equivalent of lanthanum metal and a catalytic amount of iodine gave the reductive dimerization product of 1a, a vic-diamine, in good yield. Various vic-diamines were synthesized from aldimines in this
