1-[5-(4-nitro-benzenesulfonylamino)-[1,3,4]thiadiazol-2-yl]-pyridinium betaine is a complex organic compound with a molecular formula of C16H11N5O4S3. It is characterized by a pyridinium core, which is a positively charged nitrogen-containing ring structure. The compound features a [1,3,4]thiadiazole ring, which is a five-membered ring with one sulfur and two nitrogen atoms. The thiadiazole ring is substituted at the 5-position with a 4-nitro-benzenesulfonylamino group, which introduces a nitro group and a benzene ring with a sulfonyl group attached to it. 1-[5-(4-nitro-benzenesulfonylamino)-[1,3,4]thiadiazol-2-yl]-pyridinium betaine is likely to have significant chemical reactivity due to the presence of the nitro group and the sulfonyl group, which can participate in various chemical reactions. It may be used in the synthesis of pharmaceuticals or other organic compounds due to its unique structure and reactivity.
The CAS Registry Mumber 7653-38-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,5 and 3 respectively; the second part has 2 digits, 3 and 8 respectively. Calculate Digit Verification of CAS Registry Number 7653-38: (6*7)+(5*6)+(4*5)+(3*3)+(2*3)+(1*8)=115 115 % 10 = 5 So 7653-38-5 is a valid CAS Registry Number.
