Check Digit Verification of cas no
The CAS Registry Mumber 142065-76-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,0,6 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 142065-76:
(8*1)+(7*4)+(6*2)+(5*0)+(4*6)+(3*5)+(2*7)+(1*6)=107
107 % 10 = 7
So 142065-76-7 is a valid CAS Registry Number.

Synthesis of α-amino dithioesters and endothiodipeptides
Hartke, Klaus,Barrmeyer, Stephan
, p. 251 - 256 (2007/10/03)
The α-amino ester hydrochlorides (1) are converted into N-protected α-amino amides (3), α-amino thioamides (4) and α-amino dithiomethylesters (5). Condensation of 5 with the alkali salts of α-amino acids gives rise to the endothiodipeptide alkali salts (7). Johann Ambrosius Barth 1996.
