Check Digit Verification of cas no

The CAS Registry Mumber 1609555-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,5,5 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1609555-40:
(9*1)+(8*6)+(7*0)+(6*9)+(5*5)+(4*5)+(3*5)+(2*4)+(1*0)=179
179 % 10 = 9
So 1609555-40-9 is a valid CAS Registry Number.

Linkage isomerism in transition-metal complexes of mixed (arylcarboxamido)(arylimino)pyridine ligands

Boyce, David W.,Salmon, Debra J.,Tolman, William B.

, p. 5788 - 5796 (2014/06/23)

The synthesis of a series of asymmetric mixed 2,6-disubstituted (arylcarboxamido)(arylimino)pyridine ligands and their coordination chemistry toward a series of divalent first-row transition metals (Cu, Co, and Zn) have been explored. Complexes featuring both anionic N,N,N″-carboxamido and neutral O,N,N-carboxamide coordination have been prepared and characterized by X-ray crystallography, cyclic voltammetry, and UV-visible and EPR spectroscopy. Specifically, RLM(X) (M = Cu; X = Cl-, OAc-) and RL(H)MX2 (M = Cu, Co, Zn; X = Cl-, SbF 6-) complexes that feature N,N,N″- or O,N,N-coordination are presented. Base-induced linkage isomerization from O,N,N-carboxamide to N,N,N″-carboxamido coordination is also confirmed by multiple forms of spectroscopy.
