N-phenyl-N'-sulfanilyl-guanidine, also known as sulfaguanidine or sulfamethazine, is a synthetic sulfonamide antibiotic that was first introduced in the 1940s. It is a white crystalline powder with the chemical formula C12H14N4O2S. Sulfa drugs, including sulfaguanidine, work by inhibiting bacterial synthesis of folic acid, which is essential for bacterial growth and reproduction. N-phenyl-N'-sulfanilyl-guanidine was widely used to treat various bacterial infections, particularly urinary tract infections, but its use has declined due to the emergence of antibiotic-resistant bacteria and the development of newer, more effective antibiotics. It is also used as a growth promoter in veterinary medicine, although its use in livestock has been banned in some countries due to concerns about antibiotic resistance and potential residues in food products.
The CAS Registry Mumber 6786-94-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,8 and 6 respectively; the second part has 2 digits, 9 and 4 respectively. Calculate Digit Verification of CAS Registry Number 6786-94: (6*6)+(5*7)+(4*8)+(3*6)+(2*9)+(1*4)=143 143 % 10 = 3 So 6786-94-3 is a valid CAS Registry Number.
