3,4-di-p-tolyl-[1,2,5]thiadiazole 1,1-dioxide is a chemical compound with the molecular formula C16H14N2O2S. It is a derivative of [1,2,5]thiadiazole, a five-membered heterocyclic ring containing sulfur, nitrogen, and oxygen atoms. The compound is characterized by the presence of two para-tolyl (4-methylphenyl) groups attached to the 3 and 4 positions of the thiadiazole ring, and a dioxide group (-O2) at the 1,1 position. This structure endows the compound with unique electronic and steric properties, making it potentially useful in various chemical and pharmaceutical applications, such as in the synthesis of novel materials or as a building block for more complex molecules.
The CAS Registry Mumber 3775-18-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,7 and 5 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 3775-18: (6*3)+(5*7)+(4*7)+(3*5)+(2*1)+(1*8)=106 106 % 10 = 6 So 3775-18-6 is a valid CAS Registry Number.
