4-Chlorophenyl 4-bromobenzenesulfonate is an organic compound characterized by its molecular formula C12H8BrClO3S. 4-chlorophenyl 4-bromobenzenesulfonate is a derivative of benzenesulfonic acid, where a 4-bromobenzenesulfonyl group is attached to a 4-chlorophenyl ring. It is a white crystalline solid with a melting point of approximately 150-152°C. Due to the presence of both a halogenated phenyl group and a sulfonyl group, 4-chlorophenyl 4-bromobenzenesulfonate exhibits properties of both aromatic and sulfonyl chemistry. It is used in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals, often serving as an intermediate in the preparation of more complex molecules. The compound's reactivity can be attributed to the electron-withdrawing nature of the sulfonyl group and the halogenated phenyl ring, which can participate in a range of chemical reactions, including nucleophilic substitutions and electrophilic aromatic substitutions.

Check Digit Verification of cas no

The CAS Registry Mumber 5210-50-4 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 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5210-50:
(6*5)+(5*2)+(4*1)+(3*0)+(2*5)+(1*0)=54
54 % 10 = 4
So 5210-50-4 is a valid CAS Registry Number.
