Check Digit Verification of cas no

The CAS Registry Mumber 218290-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,2,9 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 218290-86:
(8*2)+(7*1)+(6*8)+(5*2)+(4*9)+(3*0)+(2*8)+(1*6)=139
139 % 10 = 9
So 218290-86-9 is a valid CAS Registry Number.

Synthesis of optically pure 2-azetidinones having N-dehydroamino acid side-chains

Alcaide, Benito,Polanco, Concepción,Sierra, Miguel A.

, p. 416 - 418 (1998)

An efficient, three step synthesis of optically pure N-vinyl-2-azetidinones 1 starting from α- or β-amino ester imines has been developed. Stau?dinger reaction between amino ester derived imines and ketene precursors gave 2-azetidinones 2. Enolate formati
