Check Digit Verification of cas no

The CAS Registry Mumber 159972-36-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,9,7 and 2 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 159972-36:
(8*1)+(7*5)+(6*9)+(5*9)+(4*7)+(3*2)+(2*3)+(1*6)=188
188 % 10 = 8
So 159972-36-8 is a valid CAS Registry Number.

A Sulfolene-based Intramolecular Diels-Alder Approach to the Synthesis of Manzamine A

Leonard, John,Fearnley, Stephen P.,Finlay, M. Raymond,Knight, John A.,Wong, Gordon

, p. 2359 - 2362 (2007/10/02)

Synthetic studies towards manzamine A are described.A tandem sulfolene SO2 extrusion intramolecular Diels-Alder cyclisation gave the C-5 epimer of the manzamine tricyclic ABC ring system via a C-5 to C-8 diene bearing a C-5/C-6 Z-alkene.
