34257-95-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 34257-95-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,2,5 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 34257-95:
(7*3)+(6*4)+(5*2)+(4*5)+(3*7)+(2*9)+(1*5)=119
119 % 10 = 9
So 34257-95-9 is a valid CAS Registry Number.

Antitumor agents XXXVI: Structure elucidation of sesquiterpene lactones microhelenins-A, B, and C, microlenin acetate, and plenolin from Helenium microcephalum

Imakura,Lee,Sims,Wu,Hall,Furukawa,Itoigawa,Yonaha

, p. 1044 - 1049 (2007/10/02)

The antitumor sesquiterpene lactones microhelenine-A, B, and C, microlenin acetate, and plenolin were isolated from Helenium microcephalum. The structures and stereochemistry of these lactones were determined by physical methods as well as by chemical transformations and correlations. Microlenin acetate appears to be the first novel dimeric sesquiterpene lactone demonstrated to have significant antileukemic activity.
