Check Digit Verification of cas no

The CAS Registry Mumber 433304-61-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,3,3,0 and 4 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 433304-61:
(8*4)+(7*3)+(6*3)+(5*3)+(4*0)+(3*4)+(2*6)+(1*1)=111
111 % 10 = 1
So 433304-61-1 is a valid CAS Registry Number.

Synthesis, hydrolytic activation and cytotoxicity of etoposide prodrugs.

Wrasidlo, Wolf,Schroeder, Ulrike,Bernt, Kathrin,Huebener, Nicole,Shabat, Doron,Gaedicke, Gerhard,Lode, Holger

, p. 557 - 560 (2002)

Two 4'-propylcarbonoxy derivatives (2,3) of etoposide (1), a topoisomerase II inhibitor, were synthesized and evaluated as potential prodrugs for anticancer therapy. Their activation via hydrolysis mechanisms was determined as a function of pH in buffer solutions, in human serum and in the presence of carboxyl ester hydrolase. Cytotoxicity was determined on various tumor cell lines and compared to the parent compound. On cell lines exhibiting resistance to etoposide we observed an enhanced cytotoxicity of the prodrugs of up to three orders of magnitude.
