Check Digit Verification of cas no

The CAS Registry Mumber 1338468-26-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,4,6 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1338468-26:
(9*1)+(8*3)+(7*3)+(6*8)+(5*4)+(4*6)+(3*8)+(2*2)+(1*6)=180
180 % 10 = 0
So 1338468-26-0 is a valid CAS Registry Number.

The enantioselective synthesis of tetracyclic methyllycaconitine analogues

Sparrow, Kevin,Barker, David,Brimble, Margaret A.

, p. 7989 - 7999 (2011/11/07)

A new enantioselective synthesis of ABEF ring analogues of methyllycaconitine has been developed using a chiral cobalt(III) salen-catalyzed Diels-Alder reaction to form the B ring. Subsequent elaboration to form the A, E and F rings was achieved by sequential Dieckmann, Mannich and Wacker-type cyclizations to afford tetracyclic analogues in 97.5% ee.
