81440-41-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81440-41-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,4 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81440-41:
(7*8)+(6*1)+(5*4)+(4*4)+(3*0)+(2*4)+(1*1)=107
107 % 10 = 7
So 81440-41-7 is a valid CAS Registry Number.

Synthesis of a novel class of heteroaromatic amino acids and their use in the preparation of analogues of luteinizing hormone-releasing hormone
Nestor Jr.,Horner,Ho,Jones,McRae,Vickery
, p. 320 - 325 (2007/10/02)
A novel class of heterocyclic aromatic amino acids based on the 3-(2-benzimidazolyl)alanine system has been generated by chiral synthesis from D- or L-aspartic acid. The use of variously substituted o-phenylenediamines for condensation with the β-carboxyl
