Check Digit Verification of cas no

The CAS Registry Mumber 203806-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,8,0 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 203806-68:
(8*2)+(7*0)+(6*3)+(5*8)+(4*0)+(3*6)+(2*6)+(1*8)=112
112 % 10 = 2
So 203806-68-2 is a valid CAS Registry Number.

New approaches to the asymmetric synthesis of dipeptide isosteres via β-Lactam Synthon Method

Ojima, Iwao,Wang, Hong,Wang, Tao,Ng, Edward W.

, p. 923 - 926 (2007/10/03)

New and efficient synthetic routes to dipeptide isosteres with high enantiomeric purity, e.g., hydroxyethylene, dihydroxyethylene and hydroxyethylamine isosteres, have been developed via oxiranes 6 and formyloxazolines 13 derived from N-t-Boc-β-lactams 4.
