60785-23-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 60785-23-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,7,8 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 60785-23:
(7*6)+(6*0)+(5*7)+(4*8)+(3*5)+(2*2)+(1*3)=131
131 % 10 = 1
So 60785-23-1 is a valid CAS Registry Number.

Novel stereoselective phase transfer catalytic synthesis and some applications of (E)-2-chlorovinylthioarenes and hetarenes

, p. 521 - 529 (2003)

A novel two-step method for the preparation of (E)-2-chlorovinyl-thioarenes (or hetarenes) from thiols and 1,1,2-trichloroethane in the phase transfer catalytic systems solid K2CO3/solid KI/18-crown-6/xylene and solid KOH/18-crown-6/

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.
