Check Digit Verification of cas no

The CAS Registry Mumber 439912-50-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,9,1 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 439912-50:
(8*4)+(7*3)+(6*9)+(5*9)+(4*1)+(3*2)+(2*5)+(1*0)=172
172 % 10 = 2
So 439912-50-2 is a valid CAS Registry Number.

Synthesis and applications of propargyl pentafluorophenyl carbonate for peptide synthesis

Bhat, Ramakrishna G,Kérourédan, Erwan,Porhiel, Emmanuel,Chandrasekaran, Srinivasan

, p. 2467 - 2469 (2002)

Propargyl pentafluorophenyl carbonate was synthesised in quantitative yield by the reaction of propargyl chloroformate and pentafluorophenol. All the N-propargyloxycarbonyl (N-Poc) amino acids were obtained in good yield. The use of Poc-OPfp in peptide synthesis has been explored.
