Calculate Digit Verification of CAS Registry Number 1415550-81:
(9*1)+(8*4)+(7*1)+(6*5)+(5*5)+(4*5)+(3*0)+(2*8)+(1*1)=140
140 % 10 = 0
So 1415550-81-0 is a valid CAS Registry Number.

Stereoselective approach to cis -2,3-disubstituted piperidines via reduction of N -acyliminium ion intermediate: Enantioselective synthesis of (+)-(2 S,3 S)-CP-99,994

Sultane, Prakash R.,Bhat, Ramakrishna G.

, p. 11349 - 11354 (2013/02/23)

A very simple and efficient stereoselective approach to cis-2,3-disubstituted piperidines via the reduction of N-acyliminium ion intermediates is described. Application of this methodology is exemplified by the enantioselective total synthesis of (+)-(2S,3S)-CP-99,994.
