Check Digit Verification of cas no
The CAS Registry Mumber 103402-34-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,4,0 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 103402-34:
(8*1)+(7*0)+(6*3)+(5*4)+(4*0)+(3*2)+(2*3)+(1*4)=62
62 % 10 = 2
So 103402-34-2 is a valid CAS Registry Number.

, p. 4347 - 4358 (2007/10/02)
A three-step method for the synthesis of new 18,21 or 24-membered macrocyclic tetralactams with two dimethyleneoxy moieties is described. The method consists in the ring closure of a bis-secondary amine with a diamide diacid derivative activated by the th
