However, it is important to note that due to the potential health risks associated with 4,4'-SULFONYLDIPHENOL, there is an ongoing debate and research into safer alternatives for its applications, especially in consumer products that may come into direct contact with humans or the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 46765-03-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,6,7,6 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 46765-03:
(7*4)+(6*6)+(5*7)+(4*6)+(3*5)+(2*0)+(1*3)=141
141 % 10 = 1
So 46765-03-1 is a valid CAS Registry Number.

A convenient method for the one-step synthesis of symmetrical diaryl sulfones from aryl halides has been developed. A keystone of the method is the use of K2S2O5, which can be easily and safely handled, as a sulfur dioxide surrogate. The palladium catalyst bearing P(t-Bu)3 as a ligand enables formation of the desired sulfones without significant formation of byproducts.
