4'-(Dimethylsulfamoyl)sulfanilanilide, also known as Sulfamethizole, is a synthetic sulfonamide antibiotic that was widely used in the mid-20th century for its bacteriostatic properties. It works by inhibiting bacterial dihydropteroate synthase, an enzyme involved in folic acid synthesis, which is essential for bacterial growth. Sulfamethizole was particularly effective against gram-positive bacteria and was used to treat various infections, including urinary tract infections, respiratory infections, and otitis media. However, due to the rise of antibiotic resistance and the development of newer, more effective antibiotics, its use has significantly declined. It is now considered an obsolete drug in human medicine, though it may still be used in some veterinary applications.

515-67-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 515-67-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 515-67:
(5*5)+(4*1)+(3*5)+(2*6)+(1*7)=63
63 % 10 = 3
So 515-67-3 is a valid CAS Registry Number.
