N-[2-(4-nitro-phenyl)-3,6-dihydro-2H-1λ4-[1,2]thiazin-1-ylidene]-benzenesulfonamide is a complex organic compound with the molecular formula C16H13N3O4S2. It features a benzenesulfonamide group attached to a 1,2-thiazine ring, which is further fused with a phenyl group. The thiazine ring is characterized by a nitrogen atom in the 1-position and a sulfur atom in the 4-position, with the 2-position occupied by a phenyl group that is substituted with a nitro group at the para position. N-[2-(4-nitro-phenyl)-3,6-dihydro-2H-1λ4-[1,2]thiazin-1-ylidene]-benzenesulfonamide is likely to be a pharmaceutical intermediate or a chemical used in the synthesis of other complex molecules, given its structural complexity and the presence of multiple functional groups.
The CAS Registry Mumber 3947-82-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,4 and 7 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 3947-82: (6*3)+(5*9)+(4*4)+(3*7)+(2*8)+(1*2)=118 118 % 10 = 8 So 3947-82-8 is a valid CAS Registry Number.
