163595-51-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 163595-51-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,5,9 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 163595-51:
(8*1)+(7*6)+(6*3)+(5*5)+(4*9)+(3*5)+(2*5)+(1*1)=155
155 % 10 = 5
So 163595-51-5 is a valid CAS Registry Number.

Functionalization of 2-Phenylsulfonyl 1,3-Dienes via Cyclopropanation and Epoxidation. Synthesis of Oxabicyclic Systems via BF3-Induced Rearrangement of Epoxide Derivatives

Loefstroem, Claes M. G.,Ericsson, Anna M.,Bourrinet, Luc,Juntunen, Seppo K.,Baeckvall, Jan-E.

, p. 3586 - 3591 (1995)

Regioselective cyclopropanation and epoxidation of 2-phenylsulfonyl 1,3-dienes using dimethyloxosulfonium methylide ((CH3)2SOCH2) and m-chloroperbenzoic acid (m-CPBA) gave access to 3,4-epoxy-1,2-methylene-2-phenylsulfonyl alkenes.The Lewis acid-catalyzed rearrangement of these substrates using BF3*OEt2 or LiClO4 was studied.The outcome of the rearrangement appeared to be very much dependent on substrate stereochemistry and substitution pattern, since both ketones and bicyclic ethers (the oxo analogue of the tropa alkaloid skeleton) were isolated.Further functionalization of one of the bicyclic ethers (3-(phenylsulfonyl)-8-oxabicyclo-2-octene) was undertaken, proceeding with excellent stereoselectivity in all the cases investigated.This opens a way for synthesis of cis-2,5-disubstituted tetrahydrofurans.
