4219-76-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4219-76-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,1 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4219-76:
(6*4)+(5*2)+(4*1)+(3*9)+(2*7)+(1*6)=85
85 % 10 = 5
So 4219-76-5 is a valid CAS Registry Number.

Characterisation of the first authenticated organomercury hydroxide, 4-Me2NC6H4HgOH

Nicholson, Brian K.,Whitley, Sam K.

, p. 515 - 521 (2007/10/03)

4-Me2NC6H4HgOH was prepared from 4-Me2NC6H4HgOAc. Full characterisation showed that it crystallises as discrete molecules, the first example of a true organomercury hydroxide in the solid state. The structures of 4-Me2NC6H4HgOAc and (4-Me2NC6H4)2Hg are also discussed.

Synthesis and Interconversion of, and Restricted Rotation in, Phenyl Complexes of Ruthenium(II)

Probitts, E. Jane,Saunders, David R.,Stone, Michael H.,Mawby, Roger J.

, p. 1167 - 1174 (2007/10/02)

The preparation and characterization of a range of phenyl complexes of ruthenium(II) are reported.For many of the complexes there is a substantial barrier to rotation of the phenyl ligand about the metal-phenyl bond, and n.m.r. studies have shown how the rate of rotation is affected by changes in the ligands in the complexes.Reaction of complexes with phosphorus or arsenic ligands L provides a convenient route to : 31P and 13C n.m.r. studies have demonstrated the sequence of steps involved and the stereochemistry of the intermediates, showing the influence of the trans-labilizing and trans-directing effects of the phenyl ligand.
