Check Digit Verification of cas no

The CAS Registry Mumber 1439241-70-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,9,2,4 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1439241-70:
(9*1)+(8*4)+(7*3)+(6*9)+(5*2)+(4*4)+(3*1)+(2*7)+(1*0)=159
159 % 10 = 9
So 1439241-70-9 is a valid CAS Registry Number.

An alternately introduced heterometallo-supramolecular polymer: Synthesis and solid-state emission switching by electrochemical redox

Sato, Takashi,Higuchi, Masayoshi

, p. 5256 - 5258 (2013)

By utilizing different coordination properties of a lanthanide ion and a transition metal ion, a heterometallo-supramolecular polymer with Eu(iii) and Fe(ii) ions introduced alternately (polyEuFe) was precisely prepared via stepwise complexation of the metal ions to a new unsymmetrical ligand with both a dicarboxylate-substituted terpyridine and an unsubstituted terpyridine. The polymer showed unique, reversible on-off switching of the Eu(iii) luminescence by electrochemical redox of the Fe ions in the solid-state. The Royal Society of Chemistry 2013.
