5-nitro-2-(toluene-4-sulfonyl)-2H-naphtho[1,8-cd]isothiazole 1,1-dioxide is a complex organic compound characterized by its unique molecular structure. It features a naphtho[1,8-cd]isothiazole core, which is a fused ring system consisting of a naphthalene and an isothiazole. The molecule is further defined by the presence of a nitro group at the 5-position, which introduces a strong electron-withdrawing effect, and a toluene-4-sulfonyl group attached at the 2-position, providing additional complexity to the molecule's reactivity and properties. The 1,1-dioxide functional group indicates the presence of two oxygen atoms bonded to the same carbon, enhancing the molecule's stability and potentially affecting its chemical behavior. 5-nitro-2-(toluene-4-sulfonyl)-2H-naphtho[1,8-cd]isothiazole 1,1-dioxide is likely to be of interest in the fields of organic chemistry and materials science, where its specific structural features could have implications for its use in the development of new pharmaceuticals, dyes, or other specialty chemicals.
The CAS Registry Mumber 4709-33-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,0 and 9 respectively; the second part has 2 digits, 3 and 3 respectively. Calculate Digit Verification of CAS Registry Number 4709-33: (6*4)+(5*7)+(4*0)+(3*9)+(2*3)+(1*3)=95 95 % 10 = 5 So 4709-33-5 is a valid CAS Registry Number.
