Check Digit Verification of cas no

The CAS Registry Mumber 2252-71-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,5 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2252-71:
(6*2)+(5*2)+(4*5)+(3*2)+(2*7)+(1*1)=63
63 % 10 = 3
So 2252-71-3 is a valid CAS Registry Number.

Use of N-trifluoroacetyl-protected amino acid chlorides in peptide coupling reactions with virtually complete preservation of stereochemistry

Jass, Paul A.,Rosso, Victor W.,Racha, Saibaba,Soundararajan, Nachimuthu,Venit, John J.,Rusowicz, Andrew,Swaminathan, Shankar,Livshitz, Julia,Delaney, Edward J.

, p. 9019 - 9029 (2007/10/03)

The use of protected amino acid chlorides for peptide coupling reactions has long been avoided due to the extensive racemization that commonly occurs during either the acid chloride formation or the coupling reaction itself. Conditions are described which
