Check Digit Verification of cas no

The CAS Registry Mumber 133345-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,4 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 133345-56:
(8*1)+(7*3)+(6*3)+(5*3)+(4*4)+(3*5)+(2*5)+(1*6)=109
109 % 10 = 9
So 133345-56-9 is a valid CAS Registry Number.

BIOINORGANIC APPROACH TO THE CYTOCHROME OXIDASE ACTIVE SITE. STRONGLY SPIN-COUPLED COPPER(II)-IRON(III) HETERO-METAL BINUCLEAR COMPLEXES

Okawa, Hisashi,Kanda, Wakako,Kida, Sigeo

, p. 1281 - 1284 (2007/10/02)

Copper(II)-iron(III) binuclear complexes, CuFe(fsaR)Cl*nH2O, with N,N'-bis(3-carboxysalicylidene)alkanediamines (H4fsaR) were prepared and characterized.Cryomagnetic measurements indicated a considerably strong antiferromagnetic spin-exchange interaction operating between the metal ions.The exchange integrals (ca. -50 cm-1) are the largest among the copper(II)-iron(III) complexes so far reported, and hence the complexes mimic the cytochrome oxidase active center.
