Check Digit Verification of cas no

The CAS Registry Mumber 143666-05-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,6,6 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 143666-05:
(8*1)+(7*4)+(6*3)+(5*6)+(4*6)+(3*6)+(2*0)+(1*5)=131
131 % 10 = 1
So 143666-05-1 is a valid CAS Registry Number.

Synthesis and Activity against Multidrug Resistance in Chinese Hamster Ovary Cells of New Acridone-4-carboxamides

Dodic, Nerina,Dumaitre, Bernard,Daugan, Alain,Pianetti, Pascal

, p. 2418 - 2426 (2007/10/02)

A number of tricyclic carboxamides have been synthesized and tested to evaluate their ability to reverse multidrug resistance in the CHRC/5 cell line.Among them the acridone derivatives were the most potent.A key feature is the presence of a dimethoxybenzyl or phenethylamine cationic site, separated from the tricyclic lipophilic part by a carbamoylphenyl chain.Optimization led to compounds 2 orders of magnitude more active than the prototype inhibitors verapamil and amiodarone.On the basis of in vitro and in vivo activities, 9,10-dihydro-5-methoxy-9-oxo-N-phenyl>-4-acridinecarboxamide (84) has been selected for further development.
