109881-43-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109881-43-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,8 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 109881-43:
(8*1)+(7*0)+(6*9)+(5*8)+(4*8)+(3*1)+(2*4)+(1*3)=148
148 % 10 = 8
So 109881-43-8 is a valid CAS Registry Number.

Synthetic and Structural Studies on Coordination Polymers of Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) with Azelaic Acid-Bis-(phenyl hydrazide) and Azelaic Acid-Bis-(2,4-dinitrophenyl hydrazide)

Juneja, H. D.,Chakravarty, B. B.,Munshi, K. N.

, p. 257 - 259 (2007/10/02)

The coordination polymers of azelaic acid-bis-(phenyl hydrazide) and azelaic acid-bis-(2,4-dinitrophenyl hydrazide) have been prepared by the reaction of the ligands with the acetates of Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) in dimethylformamide-ethanol (4:1) medium.Thermal stability of each polymer has been investigated by thermogravimetric analysis.Characterization of these polymers has been carried out on the basis of elemental analysis, reflectance spectral (electronic), infrared spectral and magneic moment data.
