Check Digit Verification of cas no

The CAS Registry Mumber 277314-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,7,3,1 and 4 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 277314-01:
(8*2)+(7*7)+(6*7)+(5*3)+(4*1)+(3*4)+(2*0)+(1*1)=139
139 % 10 = 9
So 277314-01-9 is a valid CAS Registry Number.

Copper-mediated oxygenation of flavonolate in the presence of a tridentate N-ligand. Synthesis and crystal structures of [Cu(fla)(idpaH)]ClO4 and [Cu(idpaH)(O-bs)]ClO4, [fla = flavonolate, idpaH = 3,3'-iminobis(N,N-dimethylpropylamine), O-bs = O-benzoylsalicylate]

, p. 72 - 77 (2000)

The complexes [Cu(fla)(idpaH)]ClO4 (4) and [Cu(idpaH)(O-bs)]ClO4 (5) (fla = flavonolate, idpaH = 3,3'-iminobis(N,N-dimethylpropylamine), O-bs = O-benzoylsalicylate) have been synthesised and characterised. Complex 5 can be obtained also by the oxygenation of 4 and concomitant CO release. The structures of the compounds have been determined by X-ray diffraction. Complex 4 exhibits distorted trigonal-bipyramidal geometry around the copper(II) ion while complex 5 is distorted square-pyramidal. (C) 2000 Elsevier Science S.A.
