Check Digit Verification of cas no

The CAS Registry Mumber 140928-67-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,9,2 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 140928-67:
(8*1)+(7*4)+(6*0)+(5*9)+(4*2)+(3*8)+(2*6)+(1*7)=132
132 % 10 = 2
So 140928-67-2 is a valid CAS Registry Number.

Highly Stereoselective 3 + 2 Annulations by Cyclopropanation of Vinyl Ethers with Rhodium(II)-Stabilized Vinylcarbenoids Followed by a Formally Forbidden 1,3-Sigmatropic Rearrangement

Davies, Huw M. L.,Hu, Baihua

, p. 3186 - 3190 (2007/10/02)

A highly stereoselective 3 + 2 annulation has been developed by cyclopropanation of vinyl ethers with rhodium(II)-stabilized vinylcarbenoids to generate vinylcyclopropanes followed by a Et2AlCl-catalyzed 1,3-sigmatropic rearrangement.The success of this m
