Check Digit Verification of cas no

The CAS Registry Mumber 80919-03-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,9,1 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80919-03:
(7*8)+(6*0)+(5*9)+(4*1)+(3*9)+(2*0)+(1*3)=135
135 % 10 = 5
So 80919-03-5 is a valid CAS Registry Number.

Application of Diphenylphosphinic Carboxylic Mixed Anhydrides to Peptide Synthesis.

Ramage, Robert,Hopton, David,Parrott, Maxwell J.,Richardson, Reginald S.,Kenner, George W.,Moore, Geoffrey A.

, p. 461 - 470 (2007/10/02)

Diphenylphosphinic carboxylic mixed anhydrides formed in situ from Nα-protected amino acids and diphenylphosphinic chloride have been critically evaluated in peptide synthesis.Wherever possible, 32.4 MHz 31P n.m.r. spectroscopy has been employed to follow the rates of both mixed anhydride formation and aminolysis.
