Check Digit Verification of cas no
The CAS Registry Mumber 199614-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,6,1 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 199614-03:
(8*1)+(7*9)+(6*9)+(5*6)+(4*1)+(3*4)+(2*0)+(1*3)=174
174 % 10 = 4
So 199614-03-4 is a valid CAS Registry Number.

Synthesis and evaluation of enantiomeric purity of protected α-amino and peptide aldehydes
Mindt, Thomas,Michel, Urs,Dick
, p. 1960 - 1968 (2007/10/03)
The synthesis of enantiomerically pure Ac-Tyr-Val-Ala-Asp(O'Bu)-H dimethyl acetal ((S)-1) is reported, a protected tetrapeptide C-terminal aldehyde belonging to a class of potent, reversible inhibitors of cysteine proteases (e.g., interleukin-1β-convertin
