General Description
DEUTERIUM OXIDE-18O, also known as heavy water or 18O-labeled deuterium oxide, is a chemical compound composed of deuterium and oxygen. It is made up of one deuterium atom and one oxygen atom, with the oxygen atom being labeled with the 18O isotope. DEUTERIUM OXIDE-18O has a higher density and boiling point than regular water, and is often used in nuclear reactors as a neutron moderator. It is also used in studies of water diffusion and metabolism in biological systems, and as a tracer in medical and environmental research. Additionally, DEUTERIUM OXIDE-18O has potential applications in pharmaceuticals, organic synthesis, and as a solvent in chemical reactions.
Check Digit Verification of cas no
The CAS Registry Mumber 14674-67-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,6,7 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 14674-67:
(7*1)+(6*4)+(5*6)+(4*7)+(3*4)+(2*6)+(1*7)=120
120 % 10 = 0
So 14674-67-0 is a valid CAS Registry Number.

Matrix isolation and laser diagnostic studies of catalytic oxidation of H2 and D2 on platinum
Tevault, D. E.,Talley, L. D.,Lin, M. C.
, p. 3314 - 3319 (1980)
The reaction of hydrogen (or deuterium) and oxygen one pure polycrystalline platinum surfaces has been investigated in the 10-5 to 10-6 Torr range using the matrix isolation and laser-induced fluorescence techniques.Water,formed with a 1.1 +/- 0.2 kcal/mole activation energy, was the onyl product detected by infrared spectroscopy at catalyst temperatures between 150 and 700 deg C.Laser-induced fluorescence experiments were used to observe the production of HO radicals both in argon matrices and in the gas phase.HO production was found to have an activation energy of 31 +/- 1 kcal/mole and could only be detected escaping from the surface at catalyst temperatures above 500 deg C.The dependence of H2O and HO radical production on the partial pressures of H2 and O2 has been made.Reaction mechanisms are discussed in relation to other studies of the oxidation of hydrogen on single crystal and polycrystalline platinum surfaces.
