Check Digit Verification of cas no

The CAS Registry Mumber 1240242-86-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,2,4 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1240242-86:
(9*1)+(8*2)+(7*4)+(6*0)+(5*2)+(4*4)+(3*2)+(2*8)+(1*6)=107
107 % 10 = 7
So 1240242-86-7 is a valid CAS Registry Number.

Crystal and molecular structures of tetraaqua(di-para-oxybenzoato)iron(II) tetrahydrate

Mamedova,Rzaeva,Movsumov,Sergienko

, p. 73 - 75 (2010)

The new complex [(p-HOC6H4CO2) 2Fe(H2O)4] ? 4H2O is synthesized and studied by X-ray diffraction analysis. The Fe(II) cation is coordinated by two para-hydroxybenzoate anions through the mono-dentate mode. Four oxygen atoms of the water molecules complete the coordination polyhedron of the central atom to an octahedron. Four molecules of water of crystallization cross-link the monomers to form a polymeric structure.
