Tris(1,10-phenanthroline)chromium(II) ion, also known as Cr(phen)3^2+, is a coordination complex consisting of a chromium(II) ion (Cr^2+) coordinated with three 1,10-phenanthroline ligands. This complex is widely used in various applications, including as a catalyst in organic synthesis, a reagent in analytical chemistry, and a model for studying metal-ligand interactions. The 1,10-phenanthroline ligands are bidentate, meaning they can bind to the central metal ion through two donor atoms, in this case, the nitrogen atoms. The overall charge of the complex is +2, as the three phenanthroline ligands are neutral, and the chromium(II) ion has a +2 charge. The structure of this complex is octahedral, with the chromium(II) ion at the center and the three phenanthroline ligands occupying the six coordination sites.

Check Digit Verification of cas no

The CAS Registry Mumber 47836-39-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,7,8,3 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 47836-39:
(7*4)+(6*7)+(5*8)+(4*3)+(3*6)+(2*3)+(1*9)=155
155 % 10 = 5
So 47836-39-5 is a valid CAS Registry Number.
