Check Digit Verification of cas no
The CAS Registry Mumber 1492-21-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,9 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1492-21:
(6*1)+(5*4)+(4*9)+(3*2)+(2*2)+(1*1)=73
73 % 10 = 3
So 1492-21-3 is a valid CAS Registry Number.

Synthesis of Casein-Related Peptides on Phosphopeptides. VIII. The Synthesis of Ser(P)-Containing Peptides by Use of Z-Ser(PO3R2)-OH Derivatives
Perich, John W.,Alewood, Paul F.,Johns, R. B.
, p. 253 - 263 (2007/10/02)
The synthesis of five Z-Ser(PO3R2)-OH (R = phenyl, ethyl, methyl, benzyl, t-butyl) derivatives is described by a simple three-step synthetic procedure which features the use of ether (A) diphenyl or dialkyl phosphorochloridate/pyridine or (B) dialkyl N,N-
