Check Digit Verification of cas no

The CAS Registry Mumber 52507-64-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,5,0 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 52507-64:
(7*5)+(6*2)+(5*5)+(4*0)+(3*7)+(2*6)+(1*4)=109
109 % 10 = 9
So 52507-64-9 is a valid CAS Registry Number.

7-Aminoquinolines. A novel class of agents active against herpesviruses

Nasr,Drach,Smith,Shipman Jr.,Burckhalter

, p. 1347 - 1351 (2007/10/02)

A series of 7-aminoquinoline derivatives was synthesized and evaluated for their capacity to produce cytotoxicity in KB cells and to inhibit the replication of herpes simplex virus (HSV) type 1. All compounds tested inhibited the replication of HSV-1 with 50% inhibitory concentrations in the range of 2-50 μg/mL. The antiviral activity of many compounds, however, was separated from cytotoxicity to replicating uninfected cells by only two- to fivefold higher than those required for antiviral activity. Nonetheless, six compounds (10, 28, 29, 32, 34, and 36) were identified in which the separation was greater than fivefold. All compounds examined were more potent inhibitors of viral DNA synthesis than the cellular DNA synthesis.
