Check Digit Verification of cas no

The CAS Registry Mumber 131575-71-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,7 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131575-71:
(8*1)+(7*3)+(6*1)+(5*5)+(4*7)+(3*5)+(2*7)+(1*1)=118
118 % 10 = 8
So 131575-71-8 is a valid CAS Registry Number.

Copper-catalyzed regioselective synthesis of (E)-β-fluorovinyl sulfones

Román, Raquel,Barrio, Pablo,Mateu, Natalia,Sedgwick, Daniel M.,Fustero, Santos

, (2019)

Organofluorine compounds are finding increasing application in a variety of fields such as pharmaceutical, agrochemical, and material sciences. However, given the scarcity of fluorine-containing natural products, advancement in this area depends almost entirely on the development of new synthetic methodologies. In this article, we present the synthesis of a series of previously undescribed (E)-β-fluorovinyl sulfones via a simple copper-catalyzed addition of hydrogen fluoride to alkynyl sulfone starting materials in varying yields and E/Z selectivities. The hydrogenation of these products was also explored and compared with the hydrogenation of the related Z isomers. These new products may find interesting applications, given the versatility of vinyl sulfones in chemical synthesis and the unique properties of vinyl fluorides in biological settings.

Approaches to 2,6-Diaryl-3,7-DioxabicycloOctane Lignans via Asymmetric Synthesis of Dihydro- and Tetrahydro-furan Derivatives

Pelter, Andrew,Ward, Robert S.,Little, Gillian M.

, p. 2775 - 2790 (2007/10/02)

Cyclisation of chiral non-racemic phenylsulphonylvinyl epoxy ethers, produced using the Sharpless epoxidation reaction, has been used to prepare a series of enantiomerically enriched 2-aryl-4-(α-hydroxybenzyl)-4,5-dihydrofuran derivatives.Reduction of these compounds using triethylsilane and BF3-diethyl ether gave the corresponding tetrahydrofuran derivatives stereoselectively.Attempts to convert either the dihydro- or tetrahydro-furan derivatives into lignans belonging to the 2,6-diaryl-3,7-dioxabicyclooctane series so far proved unsuccessful.
