The chemical compound "3-[5,7-Bis(1,1-dimethylethyl)-2-oxo-3(2H)-benzofuranylidene]-5,7-bis(1,1-dimethylethyl)-2(3H)-benzofuranone" is a complex organic molecule with a molecular formula of C27H34O4. It features a benzofuran core structure, which is a type of heterocyclic compound consisting of a benzene ring fused to a furan ring. The compound is characterized by two 1,1-dimethylethyl (also known as tert-butyl) groups attached to the 5 and 7 positions of the benzofuranone ring, and another two 1,1-dimethylethyl groups attached to the 3 position of the benzofuranylidene group. The presence of these bulky substituents contributes to the compound's stability and potential applications in various chemical and pharmaceutical contexts.

75540-64-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75540-64-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,4 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 75540-64:
(7*7)+(6*5)+(5*5)+(4*4)+(3*0)+(2*6)+(1*4)=136
136 % 10 = 6
So 75540-64-6 is a valid CAS Registry Number.

Oxidative Conversions of 2,2'-Diphenoquinone Valence Isomers with 2,3-Dichloro-5,6-dicyanobenzoquinone. Synthesis and Spectroscopic Properties of (E)-Bibenzofuranylidene-2,2'-diones (Isoxindigos)

Becker, Hans-Dieter,Lingnert, Hans

, p. 1095 - 1101 (2007/10/02)

Oxepinobenzofurans derived from tetraalkyl-substituted and dialkyldimethoxy-substituted 2,2'-diphenoquinones by spontaneous valence isomerization react with 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) in the presence of water to give benzofuranyliden-2-one
