174363-68-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 174363-68-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,3,6 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 174363-68:
(8*1)+(7*7)+(6*4)+(5*3)+(4*6)+(3*3)+(2*6)+(1*8)=149
149 % 10 = 9
So 174363-68-9 is a valid CAS Registry Number.

Stereoselectivity in the Photoinduced Electron Transfer (PET) promoted intramolecular cyclisations of 1-alkenyl-2-silyl-piperidines and -pyrrolidines: Rapid construction of 1-azabicyclo[m.n.0] alkanes and stereoselective synthesis of (±)-isoretronecanol and (±)-epilupinine

Pandey, Ganesh,Reddy, Gottimukkula Devi,Chakrabarti, Debasish

, p. 219 - 224 (2007/10/03)

PET promoted cyclisations of 1-alkenyl-2-silyl-pyrrolidines and -piperidines 9a-d to 1-aza-bicyclo[m.n.0]alkanes have been found to be stereoselective. The five-membered ring formation gives predominantly cis products while six-membered rings are trans. Application of such cyclisations to the synthesis of (±)-isoretronecanol 22a, (±)-epilupinine 29 and related alkaloids has been demonstrated. Copyright 1996 by the Royal Society of Chemistry.
