Methanesulfonic acid-(4-sulfanilyl-anilide), also known as sulfanilic acid methanesulfonate or sulfamethizole, is a synthetic sulfonamide antibiotic that was widely used in the mid-20th century. It is a white crystalline powder with the chemical formula C12H14N2O3S2. methanesulfonic acid-(4-sulfanilyl-anilide) is derived from methanesulfonic acid and 4-sulfanilyl-aniline, and it functions by inhibiting bacterial synthesis of dihydrofolic acid, which is essential for bacterial growth and reproduction. Sulfamethizole was primarily used to treat urinary tract infections, respiratory infections, and other bacterial infections, but its use has declined due to the emergence of antibiotic-resistant bacteria and the development of newer, more effective antibiotics.

4426-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4426-91-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,2 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.Calculate Digit Verification of CAS Registry Number 4426-91:
(6*4)+(5*4)+(4*2)+(3*6)+(2*9)+(1*1)=89
89 % 10 = 9
So 4426-91-9 is a valid CAS Registry Number.
