Check Digit Verification of cas no

The CAS Registry Mumber 142319-75-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,3,1 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 142319-75:
(8*1)+(7*4)+(6*2)+(5*3)+(4*1)+(3*9)+(2*7)+(1*5)=113
113 % 10 = 3
So 142319-75-3 is a valid CAS Registry Number.

Synthesis of dipeptides by the photolytic coupling of chromium-aminocarbene complexes with α-amino acid esters

Miller, James R.,Pulley, Shon R.,Hegedus, Louis S.,DeLombaert, Stephane

, p. 5602 - 5607 (2007/10/02)

Photolysis of optically active chromium-aminocarbene complexes in the presence of esters of optically active α-amino acids generates dipeptides in excellent yield and with high diastereoselectivity. In this reaction, both the peptide linkage and the stere
