Check Digit Verification of cas no

The CAS Registry Mumber 1448589-73-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,8,5,8 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1448589-73:
(9*1)+(8*4)+(7*4)+(6*8)+(5*5)+(4*8)+(3*9)+(2*7)+(1*3)=218
218 % 10 = 8
So 1448589-73-8 is a valid CAS Registry Number.

Selective amination reactions of α-nitro aryl and heteroaryl enoates

Fioravanti, Stefania,Pellacani, Lucio,Vergari, Maria Cecilia

, p. 8203 - 8207 (2013/09/12)

Highly functionalized tetrasubstituted alkenes were obtained by an unexpected amination reaction promoted by ethyl nosyloxycarbamate on various α-nitro aryl and heteroaryl enoates. A nitrene is likely the aminating species responsible for the observed insertion reaction leading to (E)-β-amino α-nitro enoates as the major products, regardless of the substrate configuration. The compounds, bearing two nitrogenous functional groups in different oxidation states, can be regarded as interesting synthons. In contrast, aziridination was observed for α-nitro alkyl enoates or β-nitro allylic alcohols.
