Check Digit Verification of cas no

The CAS Registry Mumber 158419-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,4,1 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 158419-31:
(8*1)+(7*5)+(6*8)+(5*4)+(4*1)+(3*9)+(2*3)+(1*1)=149
149 % 10 = 9
So 158419-31-9 is a valid CAS Registry Number.

Studies on the Alkylation of Dipeptide Substrates

Ager, David J.,Froen, Diane E.,Klix, Russell C.,Zhi, Benxin,McIntosh, John M.,Thangarasa, Rasiah

, p. 1975 - 1982 (2007/10/02)

Alkylation of anions derived from dipeptides with a glycine at the C-terminus have been investigated.A hydrocarbon sedition in the N-terminal residue does impart some asymmetric induction.The use of a chiral ester derivative provides the potential for double asymmetric induction and good selectivity.With an aspartyl residue at the N-terminus, problems were encountered due to competing side reactions.The use of an azetidione could circumvent some of these, but the observed induction was not high.
