Check Digit Verification of cas no
The CAS Registry Mumber 34256-01-4 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 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 34256-01:
(7*3)+(6*4)+(5*2)+(4*5)+(3*6)+(2*0)+(1*1)=94
94 % 10 = 4
So 34256-01-4 is a valid CAS Registry Number.

Phenylthio-derivatives of α-methylene-γ-lactones as pro-drugs of cytotoxic agents

A series of substituted phenylthio-derivatives of grosheimin (1), a natural cytotoxic guaianolide, were investigated with the aim of providing insight into their mechanism of action as cytotoxic agents against KB cell lines. Hydrolysis data, kinetics, in the presence and in the absence of H2O2, and the valuation of lipophilicity were correlated with cytotoxicity values and with Hammett-σ-values of substituents (R) at the thiophenol ring. These compounds behave as 'pro-drugs' which release the cytotoxic agent grosheimin by sulphur-oxidation promoted by H2O2 and subsequent retro- elimination which depends on the nature and position of the R substituent.
