18433-42-6 Usage
General Description
Zinc silicofluoride is a chemical compound composed of zinc, silicon, and fluorine. It is commonly used as a source of fluoride in water fluoridation and as an additive in various industrial processes. Zinc silicofluoride is known for its ability to prevent tooth decay by strengthening tooth enamel when added to public water supplies. It is also used as a corrosion inhibitor in various industrial applications due to its ability to form a protective layer on metal surfaces. Additionally, it is used as a component in some types of ceramic and glass production. Overall, zinc silicofluoride plays a crucial role in dental health and various industrial processes.
Check Digit Verification of cas no
The CAS Registry Mumber 18433-42-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,3 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18433-42:
(7*1)+(6*8)+(5*4)+(4*3)+(3*3)+(2*4)+(1*2)=106
106 % 10 = 6
So 18433-42-6 is a valid CAS Registry Number.

Hexaaqua dipositive ions of the first transition series: New and accurate structures; expected and unexpected trends
Cotton, F. Albert,Daniels, Lee M.,Murillo, Carlos A.,Quesada, Jaime F.
, p. 4861 - 4867 (2008/10/08)
An accurate, X-ray crystallographic redetermination of the structures of both the ammonium Tutton salts and the hexafluorosilicates of the divalent hexaaqua species that are formed by the elements of the first transition series, namely, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn, is presented here. For the Tutton salts, the metal-to-water bond distances show minima at vanadium and nickel as expected from ligand field theory considerations. For the second series of compounds, vanadium and chromium deviate unexpectedly from the pattern. A comparison of the variation of the metal-to-water distances in other hexaaqua compounds is also given and the general trends are discussed. Special attention is given to the suppression of the Jahn-Teller effect in the hexaaqua hexafluorosilicate compounds of Cr(II) and Cu(II).
