Check Digit Verification of cas no

The CAS Registry Mumber 221132-37-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,1,3 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 221132-37:
(8*2)+(7*2)+(6*1)+(5*1)+(4*3)+(3*2)+(2*3)+(1*7)=72
72 % 10 = 2
So 221132-37-2 is a valid CAS Registry Number.

Diastereoselective double ring closing metathesis reactions as an approach to symmetrical bicyclodienes

Lautens,Hughes,Zunic

, p. 868 - 883 (2007/10/03)

A new class of bicyclic dienes which contain a σ plane of symmetry are efficiently prepared in a diastereoselective fashion using ring closing metathesis reactions. These molecules have potential as starting materials for a wide range of organic targets.
