Check Digit Verification of cas no

The CAS Registry Mumber 206884-21-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,8,8 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 206884-21:
(8*2)+(7*0)+(6*6)+(5*8)+(4*8)+(3*4)+(2*2)+(1*1)=141
141 % 10 = 1
So 206884-21-1 is a valid CAS Registry Number.

Studies on anti-Helicobacter pylori agents. Part 1: Benzyloxyisoquinoline derivatives

Yoshida, Yoshiki,Barrett, David,Azami, Hidenori,Morinaga, Chizu,Matsumoto, Satoru,Matsumoto, Yoshimi,Takasugi, Hisashi

, p. 2647 - 2666 (2011/05/18)

The synthesis and optimization of the anti-Helicobacter pylori activity of a novel series of benzyloxyisoquinoline derivatives that was discovered by a random screening process, are described. In the in vitro assay, compound 10c containing a 3-acetamido-2,6-dichlorobenzyl substituent was found to have extremely potent activity against H. pylori and no activity against other common bacteria. The anti-H. pylori activity of 10c was superior to that of amoxicillin (AMPC) (1) and clarithromycin (CAM) (2). However, 10c did not show in vivo efficacy in a mouse infection model; a feature attributed to the lack of strong bactericidal activity at short contact times. (C) 1999 Elsevier Science Ltd.
