Check Digit Verification of cas no
The CAS Registry Mumber 132034-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,0,3 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 132034-31:
(8*1)+(7*3)+(6*2)+(5*0)+(4*3)+(3*4)+(2*3)+(1*1)=72
72 % 10 = 2
So 132034-31-2 is a valid CAS Registry Number.

Synthesis of N-Monosubstituted -3,3'-diamines
Kaczmarek, Lukasz,Nantka-Namirski, Pawel
, p. 821 - 828 (2007/10/02)
-3,3'-diamine (1) reacts with ethyl benzimidate hydrochloride (2) to form dipyridodiazepine 3.Alkylation of compound 3 with alkyl halides 5 in KOH/DMSO/TBAB yields the corresponding N-alkyl-N'-benzoyl-bipyridinediamines 7 which, after hydrolysis, give N-monosubstituted bipyridinediamines 9.
