Check Digit Verification of cas no

The CAS Registry Mumber 405506-73-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,5,5,0 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 405506-73:
(8*4)+(7*0)+(6*5)+(5*5)+(4*0)+(3*6)+(2*7)+(1*3)=122
122 % 10 = 2
So 405506-73-2 is a valid CAS Registry Number.

A convenient route to alkaloid lipids: Application for the synthesis of a leptophylline A analogue

Koulocheri,Pitsinos,Haroutounian

, p. 111 - 115 (2007/10/03)

A synthetic route for efficient access to alkaloid lipids, using the chiral 2,3,6-trisubstituted piperidine acetaldehyde 9 as an intermediate, is reported. The utility of the synthetic route was demonstrated in the asymmetric synthesis of an unnatural analogue of Cassia leptophylla alkaloid lipid, leptophyllin A, in 16 steps and 15% overall yield starting from D-glucal.
