73306-74-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73306-74-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,3,0 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 73306-74:
(7*7)+(6*3)+(5*3)+(4*0)+(3*6)+(2*7)+(1*4)=118
118 % 10 = 8
So 73306-74-8 is a valid CAS Registry Number.

Isolation and Structural Elucidation of Four Sesquiterpenes from Chloranthus japonicus (Chloranthaceae)

Kawabata, Jun,Tahara, Satoshi,Mizutani, Junya

, p. 1447 - 1454 (2007/10/02)

The four sesquiterpenes shizukanolide (1), dehydro-shizukanolide (2), glechomanolid (3) and isofuranodiene (4) were isolated from Chloranthus japonicus Seib. (Hitori-shizuka in Japanese, Chloranthaceae).Their absolute structures have been established on the basis of their phisycal and chemical properties.Dehydro-shizukanolide showed moderate antifungal activity.

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
