Check Digit Verification of cas no

The CAS Registry Mumber 187028-22-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,0,2 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 187028-22:
(8*1)+(7*8)+(6*7)+(5*0)+(4*2)+(3*8)+(2*2)+(1*2)=144
144 % 10 = 4
So 187028-22-4 is a valid CAS Registry Number.

α-chymotrypsin-catalysed peptide synthesis via the kinetically controlled approach using activated esters as acyl donors in organic solvents with low water content: Incorporation of non-protein amino acids into peptides

, p. 82 - 86 (2007/10/03)

The α-chymotrypsin-catalyzed peptide synthesis via the kinetically controlled approach using activated esters as acyl donors in orgnanic solvents with low water content was presented. The methyl esters of N-Z derivatives of racemic non-protein amino acids were chosen as carboxy components. They allowed the peptide-bond formation and optical resolution simultaneously to yield homochiral peptides. This method is useful for the incorporation of non-protein amino acids into peptides.
