Check Digit Verification of cas no

The CAS Registry Mumber 5051-49-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,5 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5051-49:
(6*5)+(5*0)+(4*5)+(3*1)+(2*4)+(1*9)=70
70 % 10 = 0
So 5051-49-0 is a valid CAS Registry Number.

3-Acryl-7-chloro-3,4-dihydro-1,9(2H, 19H) acridinedione, 1-hydrazones as potent antimalarial agents (1,2)

Werbel,Hung,McNamara,Ortwine

, p. 363 - 370 (2007/10/02)

A series of 3-aryl-7-dihydro-1,9(2H, 10H)-acridinedione, 1-hydrazones was prepared from the corresponding acridinediones, and examined for antimalarial activity. Potent antimalarial activity against Plasmodium berghei infections in mice was found with aliphatic substituted hydrazones. Among the substituents on the phenyl ring at the 3 position of the acridine moiety particularly high activity was associated with the 4-(trifluoromethyl)phenyl group and the 2,4-dichlorophenyl group. Moreover the ring N-OH function was shown to be necessary for good biological activity. Additional structure activity relationships are also discussed.
