Check Digit Verification of cas no

The CAS Registry Mumber 77434-38-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,3 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77434-38:
(7*7)+(6*7)+(5*4)+(4*3)+(3*4)+(2*3)+(1*8)=149
149 % 10 = 9
So 77434-38-9 is a valid CAS Registry Number.

Miyazawa, Toshifumi

, p. 3661 - 3669 (2007/10/02)

The basic problems in the synthesis of peptides with N-carboxymethyl(Cm-)amino acids were investigated.Several kinds of N-protected derivatives of a free Cm-amino acid and the N-benzyloxycarbonyl (Z) derivative of its monoester were obtained by the conven
