Calculate Digit Verification of CAS Registry Number 887361-05:
(8*8)+(7*8)+(6*7)+(5*3)+(4*6)+(3*1)+(2*0)+(1*5)=209
209 % 10 = 9
So 887361-05-9 is a valid CAS Registry Number.

New method of preparation of C2F5Li and its reactions with cyclic imines and lactims: Synthesis of α-pentafluoroethyl proline

Shevchenko, Nikolay E.,Nenajdenko, Valentine G.,R?schenthaler, Gerd-Volker

, p. 390 - 396 (2008/12/21)

Addition of pentafluoroethyllithium to cyclic imines leads to pentafluoroethyl substituted pyrrolidines, piperidines and azepanes while reaction of cyclic lactims gives rise to 2-pentafluoroethyl imines. Oxidative cleavage of 2-furyl-2-pentafluoroethyl pyrrolidine has been found to be an effective method for the preparation of a racemic α-pentafluoroethyl proline.
