(E)-1-chloro-1,2-diphenyl-2-(4-tolyl)thioethene is a chemical compound with the molecular formula C21H17ClS. It is an organosulfur compound characterized by a chlorinated ethene backbone with two phenyl groups attached to the carbon atoms adjacent to the double bond. The 4-tolyl group, which is a methyl-substituted phenyl ring, is attached to the sulfur atom. (E)-1-chloro-1,2-diphenyl-2-(4-tolyl)thioethene is an example of a thioether, where the sulfur atom is bonded to two carbon atoms, one of which is part of a phenyl group. It is a colorless solid and is used in organic synthesis, particularly in the preparation of various sulfur-containing compounds and as a precursor in the synthesis of pharmaceuticals and other specialty chemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 20101-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,0 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20101-18:
(7*2)+(6*0)+(5*1)+(4*0)+(3*1)+(2*1)+(1*8)=32
32 % 10 = 2
So 20101-18-2 is a valid CAS Registry Number.

Copper-catalyzed synthesis of β-haloalkenyl chalcogenides by addition of dichalcogenides to internal alkynes and its application to synthesis of (Z)-tamoxifen

Taniguchi, Nobukazu

experimental part, p. 2782 - 2790 (2009/08/15)

A copper-catalyzed synthesis of β-haloalkenyl sulfides or selenides was carried out by addition of dichalcogenides and tetrabutylammonium halides to internal alkynes. The present reaction anti- and regio-selectively afforded the corresponding alkenyl chal
