The chemical compound "(1aR,1bS,6aS,7aS)-6-Hydroxy-1b,5-dimethyl-7-methylene-1a,1b,6,6a,7,7a-hexahydro-1H-3-oxa-cyclopropa[a]-s-indacen-4-one" is a complex organic molecule with a unique structure. It features a hexahydro-1H-3-oxa-cyclopropa[a]-s-indacen-4-one core, which is a type of tricyclic compound with a cyclopropane ring fused to a benzene ring. The molecule has a hydroxyl group at the 6-position, a methyl group at the 1b-position, and another methyl group at the 5-position. Additionally, it has a methylene group at the 7-position, which contributes to the overall stability and reactivity of the compound. This specific stereochemistry, indicated by the prefixes (1aR,1bS,6aS,7aS), describes the three-dimensional arrangement of these functional groups around the molecule's chiral centers. The compound's structure and properties make it a potential candidate for various applications in the fields of pharmaceuticals, materials science, and organic chemistry, where its unique stereochemistry and functional groups could be exploited for specific interactions and reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 7637-97-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,3 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7637-97:
(6*7)+(5*6)+(4*3)+(3*7)+(2*9)+(1*7)=130
130 % 10 = 0
So 7637-97-0 is a valid CAS Registry Number.

Studies on the Constituents of Chloranthus ssp. III. Six Sesquiterpenes from Chloranthus japonicus

Uchida, Masaaki,Koike, Yutaka,Kusano, Genjiro,Kondo, Yoshikazu,Nozoe, Shigeo,et al.

, p. 92 - 102 (2007/10/02)

Six sesquiterpene lactones (I-VI) were isolated and characterized as constituents of Chlorantus japonicus (Chloranthraceae).The lactones chloranthalactone A-E (I-V) were found to be lindenane derivatives, and lactone VI was identified as atractylenolide II.The structure of chloranthalactone C (III) was determined by X-ray chrystallographic analysis of a crystal of III in conjunction with the negative Cotton effect in the optical rotatory dispersion (ORD) curve and negative circular dichroism curve of the ketoalcohol (XII) prepared from III.The stereostructures of chlorantholactone A and B (I and II) were deduced from the ORD curves of the degradation products (VII and X).The cytotoxixities of these lactones against mouse lymphosarcoma L-5178Y cells were determined in comparison with that of helenalin, and they were found to show moderate cytotoxic effects.Keywords- Chloranthus japonicus; sesquiterpene lactones; lindendane derivatived; X-ray chrystallographic analysis; structural elucidation; cytotoxicity; mouse lymphosarcoma l-5178Y cells
