Calculate Digit Verification of CAS Registry Number 118575-48:
(8*1)+(7*1)+(6*8)+(5*5)+(4*7)+(3*5)+(2*4)+(1*8)=147
147 % 10 = 7
So 118575-48-7 is a valid CAS Registry Number.

Scope and Stereochemistry of the Tandem Intramolecular Cyclopropanation/Cope Rearrangement Sequence

Davies, Huw M. L.,McAfee, Melinda J.,Oldenburg, Claes E. M.

, p. 930 - 936 (2007/10/02)

A stereoselective synthesis of a series of fused seven-membered carbocycles was achieved by a formal intramolecular 3 + 4 cycloaddition between vinylcarbenoids, generated by rhodium(II) acetate catalyzed decomposition of vinyldiazomethanes, and dienes.The products are formed by a tandem cyclopropanation/Cope rearrangement sequence rather than a concerted process.
