The chemical compound "(3aR,3bS,6aR,7aS)-6a,7a-Dimethyl-1,6-diphenyl-3a,3b,6a,7a-tetrahydro-cyclopenta[a]pentalene-3,4,7-trione" is a organic complex molecule with a unique structure. It features a cyclopenta[a]pentalene core, which is a five-membered ring fused to a five-membered ring, creating a complex polycyclic structure. The compound is characterized by the presence of two methyl groups at the 6a and 7a positions, and two phenyl groups attached to the 1 and 6 positions. The molecule also contains a tetrahydro group, indicating the presence of four hydrogen atoms in a saturated hydrocarbon chain. Additionally, it has three carbonyl groups (trione) at the 3, 4, and 7 positions, which contribute to its reactivity and functional properties. (3aR,3bS,6aR,7aS)-6a,7a-Dimethyl-1,6-diphenyl-3a,3b,6a,7a-tetrahydro-cyclopenta[a]pentalene-3,4,7-trione is a specific stereoisomer, with the R and S configurations at the 3a, 3b, 6a, and 7a positions, which determine its three-dimensional structure and potential biological activity.

Check Digit Verification of cas no

The CAS Registry Mumber 73843-52-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,8,4 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73843-52:
(7*7)+(6*3)+(5*8)+(4*4)+(3*3)+(2*5)+(1*2)=144
144 % 10 = 4
So 73843-52-4 is a valid CAS Registry Number.

REMARKABLY FAST CYCLOREVERSION IN METHOXY SUBSTITUTED COOKSON'S CAGE KETONES ASSISTED BY THE CAPTO-DATIVE SUBSTITUENT EFFECT AND BY THE THROUGH-BOND INTERACTION

Okamoto, Yasushi,Kanematsu, Ken,Fujiyoshi, Teruyo,Osawa, Eiji

, p. 5645 - 5648 (2007/10/02)

1,7-Dimethoxy groups in Cookson's pentacyclic cage derivates (2 and 5) accelerate the thermal cycloreversion, possibly by means of the unusual lengthening of C1-C7 bond and the synergetic capto-dative stabilization of 1,4-diradical (7 and 8).

THE ROLE OF THROUGH-BOND INTERACTION IN THERMAL BEHAVIOR OF CAGE MOLECULES

Okamoto, Yasushi,Harano, Kazunobu,Yasuda, Masami,Osawa, Eiji,Kanematsu, Ken

, p. 2526 - 2529 (2007/10/02)

The cage triketone 2 revealed different reactivities toward the thermal condition according to the substituents: the cyclobutane ring cleavage for alkyl substituents and decarbonylation for methoxycarbonyl ones.The X-ray crystallographic study for the derivative of 2b showed a significantly long (1.635(7) Angstroem) C(Ph)-C(Ph) ? bond.The reaction mechanisms are discussed in terms of frontier molecular orbital (FMO) theory combined with the results of the molecular mechanics and semiempirical MNDO molecular calculations.KEYWORDS - decarbonylation; cyclobutane ring cleavage; through-bond interaction; frontier molecular orbital; bond elongation
