The chemical "6,6'-{5-[2-(3-ethyl-4,5-diphenyl-3H-thiazol-2-ylidene)-ethylidene]-4,4'-dioxo-2'-thioxo-dihydro-[2,5']bithiazolylidene-3,3'-diyl}-bis-hexanoic acid dibutyl ester" is a complex organic compound with a molecular formula of C40H40N2O6S4. It is characterized by a bithiazolylidene core, which is a heterocyclic structure containing two thiazole rings connected through a dihydro-bithiazolylidene bridge. The compound features a hexanoic acid group at each end, which is esterified with butyl groups, and a 3-ethyl-4,5-diphenyl-thiazol-2-ylidene moiety that extends from the core structure. This molecule is likely to be a derivative of a dye or a complex organic pigment, given its structural complexity and the presence of conjugated systems that can absorb light, potentially leading to coloration. The specific properties and applications of 6,6'-{5-[2-(3-ethyl-4,5-diphenyl-3H-thiazol-2-ylidene)-ethylidene]-4,4'-dioxo-2'-thioxo-dihydro-[2,5']bithiazolylidene-3,3'-diyl}-bis-hexanoic acid dibutyl ester would depend on its ability to interact with light and its solubility in various media, which are not detailed in the provided information.
The CAS Registry Mumber 6562-46-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,6 and 2 respectively; the second part has 2 digits, 4 and 6 respectively. Calculate Digit Verification of CAS Registry Number 6562-46: (6*6)+(5*5)+(4*6)+(3*2)+(2*4)+(1*6)=105 105 % 10 = 5 So 6562-46-5 is a valid CAS Registry Number.
