Check Digit Verification of cas no

The CAS Registry Mumber 1010857-57-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,0,8,5 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1010857-57:
(9*1)+(8*0)+(7*1)+(6*0)+(5*8)+(4*5)+(3*7)+(2*5)+(1*7)=114
114 % 10 = 4
So 1010857-57-4 is a valid CAS Registry Number.

Synthesis of N-(5,7-diamino-3-phenyl-quinoxalin-2-yl)-3,4,5-substituted anilines and N-[4[(5,7-diamino-3-phenylquinoxalin-2-yl)amino]benzoyl]-l-glutamic acid diethyl ester: Evaluation of in vitro anti-cancer and anti-folate activities

, p. 189 - 203 (2008/09/17)

Several diamino quinoxalines were designed, synthesized and evaluated as anti-tumor agents. Two compounds showed the most potent cytotoxic activities against the leukemia CCRF-CEM cell line (GI50 50 = 0.03 μM), respectively, with comparable/better activities than Methotrexate (MTX). Docking calculations of the complexes of hDHFR with the most active compounds identified the binding mode of the described molecules with respect to MTX.
