Check Digit Verification of cas no
The CAS Registry Mumber 151158-42-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,1,5 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 151158-42:
(8*1)+(7*5)+(6*1)+(5*1)+(4*5)+(3*8)+(2*4)+(1*2)=108
108 % 10 = 8
So 151158-42-8 is a valid CAS Registry Number.

A general route for the synthesis of enantiopure indolizidine alkaloids from α-amino acids. Total synthesis of (+)-Monomorine
Angle, Steven R.,Guy Breitenbucher
, p. 3985 - 3988 (2007/10/02)
The ant trail pheromone (+)-Monomorine was synthesized in 9 steps from N-t-BOC-L-alanine ethyl ester. The key step of the synthesis is the conformationally restricted Claisen rearrangement of lactone 9 to pipecolic ester 11.
