"N-{4-[5-(3-nitro-phenyl)-[1,3,4]thiadiazol-2-ylsulfamoyl]-phenyl}-phthalamic acid" is a complex organic compound with the molecular formula C21H13N4O7S2. It features a phthalamic acid core, which is a derivative of phthalic acid, with a sulfamoyl group attached to a phenyl ring. This phenyl ring is further substituted with a 5-(3-nitro-phenyl)-[1,3,4]thiadiazol-2-yl group, which adds a sulfur-containing heterocycle to the structure. The compound's complexity arises from the presence of multiple functional groups, including nitro, sulfamoyl, and thiadiazole moieties, which contribute to its potential reactivity and applications in various chemical and pharmaceutical contexts.
The CAS Registry Mumber 864-34-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,6 and 4 respectively; the second part has 2 digits, 3 and 4 respectively. Calculate Digit Verification of CAS Registry Number 864-34: (5*8)+(4*6)+(3*4)+(2*3)+(1*4)=86 86 % 10 = 6 So 864-34-6 is a valid CAS Registry Number.
