83143-46-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83143-46-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,1,4 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 83143-46:
(7*8)+(6*3)+(5*1)+(4*4)+(3*3)+(2*4)+(1*6)=118
118 % 10 = 8
So 83143-46-8 is a valid CAS Registry Number.

Zanotti, G.,Pinnen, F.,Lucente, G.
, p. 5481 - 5484 (2007/10/02)
Cyclization of di- and tripeptides containing cysteine as N-terminal residue is reported.The preferred cyclization patterns and the nature of the products (diketopiperazine, aza-cyclol, peptide thiolactone) are discussed.
