5216-43-3

Trans-1,2-bis-(4-chlorophenyl)-1,2-bis-benzylsulfonyl-ethylene, also known as 1,2-bis(4-chlorophenyl)-1,2-bis(phenylmethylsulfonyl)ethene, is a complex organic compound characterized by its unique molecular structure. It features a central ethylene (C2H4) backbone with two benzylsulfonyl groups attached to each carbon atom. These benzylsulfonyl groups are themselves composed of a benzene ring and a sulfonyl group (-SO2-), with the sulfonyl group connected to a methyl group (-CH3). Additionally, each benzene ring in the benzylsulfonyl groups has a chlorine atom attached at the para position (4-chlorophenyl). This chemical is known for its potential applications in the synthesis of various pharmaceuticals and agrochemicals, particularly due to its ability to act as a precursor in the formation of other compounds. The trans configuration indicates that the two chlorine-substituted phenyl rings are on opposite sides of the ethene double bond, which can influence the compound's physical and chemical properties.

5216-43-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5216-43-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,1 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5216-43:
(6*5)+(5*2)+(4*1)+(3*6)+(2*4)+(1*3)=73
73 % 10 = 3
So 5216-43-3 is a valid CAS Registry Number.
