Check Digit Verification of cas no

The CAS Registry Mumber 226993-35-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,6,9,9 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 226993-35:
(8*2)+(7*2)+(6*6)+(5*9)+(4*9)+(3*3)+(2*3)+(1*5)=167
167 % 10 = 7
So 226993-35-7 is a valid CAS Registry Number.

Cobalt-mediated cycloisomerization of δ-substituted ε-acetylenic β- ketoesters construction of angular triquinane by a sequence ene/Pauson-Khand reactions

Renaud, Jean-Luc,Aubert, Corinne,Malacria, Max

, p. 5113 - 5128 (2007/10/03)

The preparation of δ-substituted ε-acetylenic β-ketoesters is fully described. Their cobalt-mediated Conia-ene reactions led to variously functionalized methylenecyclopentanes in high yields land with a moderate control of the 1,4 diastereoselectivity. A sequence involving the cobalt- mediated ene and Pauson-Khand reactions is presented and allowed the construction of the angular triquinane framework.
