Check Digit Verification of cas no

The CAS Registry Mumber 158146-79-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,1,4 and 6 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 158146-79:
(8*1)+(7*5)+(6*8)+(5*1)+(4*4)+(3*6)+(2*7)+(1*9)=153
153 % 10 = 3
So 158146-79-3 is a valid CAS Registry Number.

The tandem cycloaddition chemistry of nitroalkenes. A novel synthesis of (-)-hastanecine

Denmark,Thorarensen

, p. 5672 - 5680 (1994)

A short and efficient asymmetric synthesis of the pyrrolizidine necine base (-)-hastanecine is described. The key reaction in the synthesis is a sequential inter [4 + 2]/inter [3 + 2] cycloaddition. The Lewis acid promoted [4 + 2] cycloaddition between 2-
