Check Digit Verification of cas no

The CAS Registry Mumber 31847-22-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,8,4 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 31847-22:
(7*3)+(6*1)+(5*8)+(4*4)+(3*7)+(2*2)+(1*2)=110
110 % 10 = 0
So 31847-22-0 is a valid CAS Registry Number.

Pyrrolo-quinoline derivatives as potential antineoplastic drugs

Ferlin,Gatto,Chiarelotto,Palumbo

, p. 1415 - 1422 (2007/10/03)

Some novel pyrrolo-quinoline derivatives have been synthesized as potential antineoplastic agents. They contain an angular aromatic tricyclic or tetracyclic system, to which the methanesulfon-anisidide side chain typical of amsacrine as such, or lacking the m-methoxy substituent, is connected. A methyl group can be present at position 7 of the pyrrolo-quinoline ring. The novel compounds exhibit interesting cell growth inhibitory properties when tested against the NCI panel of cell lines, in particular those obtained from solid tumors like CNS-, melanoma- and prostate-derived cells. The mechanism of cytotoxic action does not seem to be related to topoisomerase II poisoning ability. Most active proved to be compound 4a, which lacks both methyl and methoxy substituents, followed by 5a, having the methoxy group only. Biological activity is less pronounced in the tetracyclic family of derivatives 6 and 7. Copyright (C) 2000 Elsevier Science Ltd.
