Check Digit Verification of cas no

The CAS Registry Mumber 728041-76-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,8,0,4 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 728041-76:
(8*7)+(7*2)+(6*8)+(5*0)+(4*4)+(3*1)+(2*7)+(1*6)=157
157 % 10 = 7
So 728041-76-7 is a valid CAS Registry Number.

Incorporation of the α-mercapto acid unit into peptides

Pumpor, Ksenia,Spengler, Jan,Albericio, Fernando,Haas, Alois,Burger, Klaus

, p. 1088 - 1092 (2004)

Incorporation of α-mercapto acid units into the backbone of potential drug candidates improves the metal ion complexing properties. So far, only the methodology for the N-terminal incorporation of mercapto acid units into peptides has been described. Now, we report on a modified strategy for the incorporation of the α-mercapto acid unit into any position of a peptide backbone starting from hexafluoroacetone-protected thiomalic acid. Concomitantly with the incorporation of the α-mercapto unit the direction of the peptide chain is inverted.
