3-nitro-7,12-diphenyl-7,12-dihydro-7,12-epoxidobenzo[4,5][1,2,3]thiadiazolo[2,3-b]phthalazine 5,5-dioxide is a complex organic compound with a unique chemical structure. It is characterized by the presence of a benzo[4,5][1,2,3]thiadiazolo[2,3-b]phthalazine core, which is a fused ring system containing both thiadiazole and phthalazine moieties. The molecule features a 7,12-dihydro-7,12-epoxide group, indicating the presence of an epoxide ring at the 7,12 positions, and a 5,5-dioxide group, suggesting the presence of two oxygen atoms at the 5 position. Additionally, the compound has two phenyl groups attached at the 7 and 12 positions, which contribute to its overall stability and reactivity. 3-nitro-7,12-diphenyl-7,12-dihydro-7,12-epioxido-benzo[4,5][1,2,3]thiadiazolo[2,3-b]phthalazine 5,5-dioxide is likely to be of interest in the field of organic chemistry, potentially for its unique properties or as a precursor in the synthesis of other complex molecules.
The CAS Registry Mumber 2656-03-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,5 and 6 respectively; the second part has 2 digits, 0 and 3 respectively. Calculate Digit Verification of CAS Registry Number 2656-03: (6*2)+(5*6)+(4*5)+(3*6)+(2*0)+(1*3)=83 83 % 10 = 3 So 2656-03-3 is a valid CAS Registry Number.
