75040-70-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75040-70-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,0,4 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75040-70:
(7*7)+(6*5)+(5*0)+(4*4)+(3*0)+(2*7)+(1*0)=109
109 % 10 = 9
So 75040-70-9 is a valid CAS Registry Number.

Synthesis of Isomeric N-Benzyl Derivatives of 1,2-Propanediamine
Kurganov, Alexandr,Zhuchkova, Lydmila,Davankov, Vadim
, p. 786 - 790 (2007/10/02)
Benzaldehyde reacts with the 1-amino group of 1,2-propanediamine (1) to give a Schiff base much more readily than with the 2-amino group.This difference permits synthesis of all the isomeric mono-and dibenzyl derivatives of racemic and chiral 1,2-propaned
