4431-68-9 Usage
General Description
3-amino-N-(phenylsulphonyl)benzenesulphonamide is a chemical compound that has the molecular formula C12H12N2O4S2. It is a sulfonamide derivative, and is commonly used as a carbonic anhydrase inhibitor, meaning it blocks the action of carbonic anhydrase enzymes in the body. This can have a range of effects, including reducing the production of aqueous humor in the eye, which is useful in the treatment of glaucoma. The chemical is also used in the treatment of certain types of seizures and as a diuretic. Additionally, it has shown potential as a therapeutic agent for certain types of cancer.
Check Digit Verification of cas no
The CAS Registry Mumber 4431-68-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,3 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4431-68:
(6*4)+(5*4)+(4*3)+(3*1)+(2*6)+(1*8)=79
79 % 10 = 9
So 4431-68-9 is a valid CAS Registry Number.
