Bis-<2-iod-phenyl>-sulfon, also known as 4,4'-diiodobiphenyl sulfone, is an organic compound characterized by its chemical formula C12H8I2O2S. It features a biphenyl core with two iodine atoms attached to the 2-position of each phenyl ring and a sulfone group (-SO2-) connecting the two phenyl rings. Bis-<2-iod-phenyl>-sulfon is often used as a precursor in the synthesis of various pharmaceuticals and agrochemicals due to its unique structure and reactivity. The presence of iodine atoms can enhance the lipophilicity and metabolic stability of the final products, making it a valuable building block in the development of new drugs and chemical compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 2236-51-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,3 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2236-51:
(6*2)+(5*2)+(4*3)+(3*6)+(2*5)+(1*1)=63
63 % 10 = 3
So 2236-51-3 is a valid CAS Registry Number.
