Check Digit Verification of cas no

The CAS Registry Mumber 139746-36-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,7,4 and 6 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139746-36:
(8*1)+(7*3)+(6*9)+(5*7)+(4*4)+(3*6)+(2*3)+(1*6)=164
164 % 10 = 4
So 139746-36-4 is a valid CAS Registry Number.

Design Of An Affinity-based Nα-amino Protecting Group For Peptide Synthesis: Tetrabenzofluorenyl-17-methyl urethanes (TBfmoc)

Ramage, Robert,Raphy, Gilles

, p. 385 - 388 (2007/10/02)

A new Nα-amino protecting group (Tbfmoc) has been designed to allow selective adsorption to porous graphitised carbon, thus allowing facile separation of Nα-acetylated trunctated peptides generated as impurities in solid phase peptide synthesis.
