The chemical compound "9-nitro-5,5-dioxo-6,6a-dihydro-5H-5λ6-benzo[5,6][1,2,4]thiadiazino[3,4-a]isoindol-11-one" is a complex organic molecule with a unique structure. It features a benzo[5,6][1,2,4]thiadiazino[3,4-a]isoindol-11-one core, which is a fused ring system incorporating both benzene and thiadiazine rings. The molecule is characterized by the presence of a nitro group at the 9-position, which introduces a strong electron-withdrawing effect, and a dihydro group at the 6,6a-positions, indicating the presence of two hydrogen atoms in a partially saturated ring. The compound also has two oxygen atoms at the 5,5-positions, forming a dioxo group, which contributes to the molecule's reactivity and stability. 9-nitro-5,5-dioxo-6,6a-dihydro-5H-5λ6-benzo[5,6][1,2,4]thiadiazino[3,4-a]isoindol-11-one is likely to be of interest in the field of organic chemistry, potentially for its pharmacological properties or as a synthetic intermediate in the preparation of other complex molecules.
The CAS Registry Mumber 5118-93-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,1 and 8 respectively; the second part has 2 digits, 9 and 3 respectively. Calculate Digit Verification of CAS Registry Number 5118-93: (6*5)+(5*1)+(4*1)+(3*8)+(2*9)+(1*3)=84 84 % 10 = 4 So 5118-93-4 is a valid CAS Registry Number.
