Check Digit Verification of cas no

The CAS Registry Mumber 119289-79-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,2,8 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 119289-79:
(8*1)+(7*1)+(6*9)+(5*2)+(4*8)+(3*9)+(2*7)+(1*9)=161
161 % 10 = 1
So 119289-79-1 is a valid CAS Registry Number.

Synthesis and antiarrhythmic activity of disubstituted phenylpyridine derivative

Shigyo,Sato,Shibuya,Takahashi,Yamaguchi,Sonoki,Ohta

, p. 1573 - 1582 (2007/10/02)

A series of disubstituted phenylpyridine derivatives was synthesized and their antiarrhythmic effects against chloroform-induced ventricular arrhythmias in mice were examined. Among them, 2- and 3-[2-(3- aminobutyramido)-4-(2,2,2-trifluoroethoxy)phenyl]pyridines (23h, 24h) and 3- [2-(3-aminobutyramido)-4-ethoxyphenyl]pyridine (24i) showed potent antiarrhythmic activity. They had approximately twice the potency of mexiletine (III). Compound 24i was selected from this series as a candidate for further development; it was found to have a class I B electrophysiological character and to show a slow kinetic rate-dependent block (RDB) of the sodium channel in cardiac muscle.
