Check Digit Verification of cas no

The CAS Registry Mumber 111920-18-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,9,2 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 111920-18:
(8*1)+(7*1)+(6*1)+(5*9)+(4*2)+(3*0)+(2*1)+(1*8)=84
84 % 10 = 4
So 111920-18-4 is a valid CAS Registry Number.

Complexes of Group (IV) Metals with 5,5'-Methylene-bis(salicylaldehyde) and Its Schiff Base with Hydrazine

Siddiqi, K. S.,Khan, N. H.,Kureshy, R. I.,Tabassum, S.,Zaidi, S. A. A.

, p. 492 - 494 (2007/10/02)

5,5'-Methylene-bis(salicylaldehyde) (I) and its schiff base (II) with hydrazine hydrate have been synthesized.Group (IV) metal complexes with (I) and (II) have been prepared and characterized on the basis of elemental analysis, IR spectroscopy, conductance measurement and molecular weight determination.Molar conductivities of their millimolar solutions in DMSO indicate the complexes to be non-ionic.On the basis of IR spectral studies, an octahedral structure has been proposed for the complexes of (I) and (II).
