Check Digit Verification of cas no

The CAS Registry Mumber 154159-03-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,1,5 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 154159-03:
(8*1)+(7*5)+(6*4)+(5*1)+(4*5)+(3*9)+(2*0)+(1*3)=122
122 % 10 = 2
So 154159-03-2 is a valid CAS Registry Number.

A Simple Method for Amide Formation from Protected Amino Acids and Peptides

Chen, Shui-Tein,Wu, Shih-Hsiung,Wang, Kung-Tsung

, p. 37 - 38 (2007/10/02)

Amide formation from protected amino acids and peptides is directly and simply achieved by using 1-hydroxybenzotriazole as activating agent and treating the intermediate O-(benzotriazol-1-yl) derivative ("active ester") in situ with 25percent ammonium hydroxide solution.
