Check Digit Verification of cas no

The CAS Registry Mumber 137604-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,6,0 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 137604-22:
(8*1)+(7*3)+(6*7)+(5*6)+(4*0)+(3*4)+(2*2)+(1*2)=119
119 % 10 = 9
So 137604-22-9 is a valid CAS Registry Number.

SYNTHESIS OF CHIRAL INDOLIZINES AS BICYCLIC ERGOLINE ANALOGUES

Gmeiner, Peter

, p. 1499 - 1504 (1991)

An efficient synthesis of the enantiomerically pure aminoindolizine (3) by a triflic anhydride assisted cyclization of the 1,3-amino alcohol (6) is reported. 6 can be readily derived from L-asparagine (4) via the O-activated β-homoserine equivalent (7).
