5,5'-sulfonyl-bis-benzofuroxan, also known as dibenzofuroxan or DBF, is a chemical compound with the molecular formula C20H12N4O5S2. It is a white crystalline solid that is soluble in organic solvents such as dimethyl sulfoxide (DMSO) and dimethylformamide (DMF). DBF is a potent inhibitor of various enzymes, including nitric oxide synthase (NOS) and xanthine oxidase (XO), making it a valuable research tool in the study of these enzymes and their roles in physiological processes. It is also used as a reagent for the detection of nitric oxide (NO) due to its ability to react with NO to form a stable, colored product. The compound is synthesized through a series of chemical reactions involving benzofuroxan and sulfonyl chloride, and its structure and properties have been well-characterized through various analytical techniques.

Check Digit Verification of cas no

The CAS Registry Mumber 973-57-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,7 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 973-57:
(5*9)+(4*7)+(3*3)+(2*5)+(1*7)=99
99 % 10 = 9
So 973-57-9 is a valid CAS Registry Number.
