Check Digit Verification of cas no

The CAS Registry Mumber 158634-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,6,3 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 158634-20:
(8*1)+(7*5)+(6*8)+(5*6)+(4*3)+(3*4)+(2*2)+(1*0)=149
149 % 10 = 9
So 158634-20-9 is a valid CAS Registry Number.

A short, enantioselective synthesis of (-)-epilupinine from proline via a spirocyclic ammonium ylide

Naidu,West

, p. 16565 - 16574 (1997)

Diazoketone 5b, available in one step from proline benzyl ester, underwent conversion to quinolizidine 8b with high diastereoselectivity (19:1 8b/7b) and in surprisingly high enantiomeric excess (75%). The key step presumably occurs via spirocyclic ylide
