1,5-Di-(p-tolyl)-3-phenylsulfonylformazan is a complex organic compound with the chemical formula C25H24N4O2S. It is a derivative of formazan, which is a class of compounds formed by the coupling of diazonium salts with phenols or enols. This particular formazan features two p-tolyl groups (each consisting of a methyl group attached to a phenyl ring) at the 1 and 5 positions, and a phenylsulfonyl group at the 3 position. The phenylsulfonyl group is a phenyl ring attached to a sulfonyl group (-SO2-), which in turn is connected to the formazan core. 1,5-Di-(p-tolyl)-3-phenylsulfonylformazan is known for its potential applications in the field of chemistry, particularly in the synthesis of various organic compounds and as a reagent in chemical reactions. Its structure and properties make it a valuable tool for researchers in organic synthesis and related fields.

Check Digit Verification of cas no

The CAS Registry Mumber 7134-35-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,3 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7134-35:
(6*7)+(5*1)+(4*3)+(3*4)+(2*3)+(1*5)=82
82 % 10 = 2
So 7134-35-2 is a valid CAS Registry Number.
