Check Digit Verification of cas no

The CAS Registry Mumber 340268-50-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,0,2,6 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 340268-50:
(8*3)+(7*4)+(6*0)+(5*2)+(4*6)+(3*8)+(2*5)+(1*0)=120
120 % 10 = 0
So 340268-50-0 is a valid CAS Registry Number.

Synthesis and pharmacological evaluation of novel non-lactone analogues of camptothecin

Hautefaye, Patrick,Cimetiere, Bernard,Pierre, Alain,Leonce, Stephane,Hickman, John,Laine, William,Bailly, Christian,Lavielle, Gilbert

, p. 2731 - 2735 (2007/10/03)

Ten novel camptothecin (CPT) derivatives devoid of the lactone function in the E-ring were synthesized and evaluated as anticancer agents. Several of these CPT analogues bearing a five-membered E-ring are potent inhibitors of the DNA relaxation and cleavage reactions catalyzed by topoisomerase I and exhibit promising cytotoxic activities with IC50 values in the nM range. This is the first successful design of lactone-free CPT, providing thus a new avenue to the development of topoisomerase I targeted antitumor agents.
