General Description
4,4'-Dicyanodiphenylsulfone is a chemical compound consisting of two benzene rings connected by a sulfonyl group and each ring bearing a nitrile group. It is primarily used as a monomer in the production of high-performance polymers, such as polyarylethersulfones, which are known for their high thermal stability, mechanical strength, and chemical resistance. Additionally, 4,4'-Dicyanodiphenylsulfone is used as a crosslinking agent in polymerization reactions to improve the physical and chemical properties of the resulting polymers. 4,4'-DICYANODIPHENYLSULPHONE is also employed as a raw material in the synthesis of dyes, pigments, and pharmaceuticals. Due to its strong electron-withdrawing nitrile groups, 4,4'-Dicyanodiphenylsulfone is also utilized in organic chemistry as a building block for various organic synthesis reactions.
Check Digit Verification of cas no
The CAS Registry Mumber 6461-99-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,6 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6461-99:
(6*6)+(5*4)+(4*6)+(3*1)+(2*9)+(1*9)=110
110 % 10 = 0
So 6461-99-0 is a valid CAS Registry Number.

Synthesis of symmetrical diaryl sulfone by homocoupling of sodium arylsulfinate
Peng, Yao
, p. 265 - 268 (2014/06/09)
An efficient practical homocoupling reaction of sodium arylsulfinate promoted by Cu(II) is reported whereby symmetrical diaryl sulfone derivatives are obtained with high selectivity and reactivity by intermolecular cross-coupling. This homocoupling reacti
