Calculate Digit Verification of CAS Registry Number 203871-75:
(8*2)+(7*0)+(6*3)+(5*8)+(4*7)+(3*1)+(2*7)+(1*5)=124
124 % 10 = 4
So 203871-75-4 is a valid CAS Registry Number.

Preparation and ring-opening reactions of N-diphenylphosphinyl aziridines

Cantrill, Alex A.,Osborn, Helen M. I.,Sweeney, Joseph

, p. 2181 - 2208 (2007/10/03)

Monochiral N-Diphenyphosphinyl aziridines ('N-Dpp azinidines') may efficiently be prepared from monochiral 2-aminoalcohols. Such aziridines undergo ring-opening reaction with a variety of nucleophiles in good yield. Dephosphinylation is accomplished under mild conditions.
