Check Digit Verification of cas no

The CAS Registry Mumber 459409-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,9,4,0 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 459409-89:
(8*4)+(7*5)+(6*9)+(5*4)+(4*0)+(3*9)+(2*8)+(1*9)=193
193 % 10 = 3
So 459409-89-3 is a valid CAS Registry Number.

Synthesis and antioxidant evaluation of Schiff bases derived from 2,6-pyridinedicarboxylic acid

Molnar, Maja,Cacic, Milan,Zrinusic, Sanja Zec

, p. 401 - 410 (2012)

A series of novel Schiff bases derived from dipicolinic acid was synthesized and evaluated for antioxidant and iron chelating activity. In most cases Schiff bases derived from di-hydrazide showed higher antioxidant activity than the ones derived from mono-hydrazide and some of them are very promising considering the fact of being better antioxidants than the standards used in the investigation. For iron chelating activity substituents had a greater impact on the activity than mono or di-hydrazide skeleton.
