The chemical compound "10-[2,3-Bis[3,5-bis(1,1-dimethylethyl)-4-oxo-2,5-cyclohexadien-1-ylidene]cyclopropylidene]anthracen-9(10H)-one" is a complex organic molecule with a molecular formula of C34H38O2. It is characterized by a central anthracene ring system, which is a tricyclic aromatic hydrocarbon. The compound features two cyclohexadienylidene moieties attached to the 2,3-positions of the central cyclopropane ring. Each of these cyclohexadienylidene groups has two tert-butyl (1,1-dimethylethyl) groups at the 3,5-positions and a carbonyl group at the 4-position. The compound is a derivative of anthraquinone, with the carbonyl group at the 10-position and a hydrogen at the 9-position, indicating a 9(10H)-anthracenone structure. This molecule is known for its potential applications in various fields, including as a dye or a precursor in the synthesis of other complex organic compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 69828-92-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,8,2 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 69828-92:
(7*6)+(6*9)+(5*8)+(4*2)+(3*8)+(2*9)+(1*2)=188
188 % 10 = 8
So 69828-92-8 is a valid CAS Registry Number.

Polyanthraquinocyclopropanes, Dianthraquinocyclopropanone, and Dianthraquinoethylene. Synthesis and Properties

Benham, Judith L.,West, Robert,Norman, John A. T.

Tris(9-anthron-10-ylidene)cyclopropane (7c) was prepared by the Friedel-Crafts reaction of 9-methoxyanthracene with trichloropropenium tetrachloroaluminate, followed by demethylation and oxidation of the resulting bis(9-hydroxy-10-anthryl)cyclopropenylidenanthrone.The corresponding triquinocyclopropanes with one or two anthraquino qroups replaced by 4-oxo-3,5-di-tert-butyl-2,5-cyclohexadien-1-ylidene groups (7a,b) were prepared by stepwise addition of 9-methoxyanthracene and 2,6-di-tert-butylphenol.Reaction of 2 equiv of 9-methoxyanthracene in an analogous fashion resulted in 2,3-bis(9-anthron-10-ylidene)cyclopropanone (8), which loses carbon monoxide photolytically to form dianthraquinoethylene (9).These materials are intensely colored, highly conjugated solids with electronic absorptions in the near infrared.Spectroscopic properties and results of Hueckel MO calculations are reported.
