General Description
Digold oxide, also known as gold(I,III) oxide, is a chemical compound with the formula Au2O3. It is a rare and unstable oxide of gold, consisting of two gold atoms per molecule. Digold oxide is a dark brown solid and is thermally unstable, decomposing to gold metal and oxygen at temperatures above 160°C. It is typically produced by reacting gold with ozone or by heating gold(III) hydroxide. While digold oxide has limited practical applications due to its instability, it has been of interest in the field of nanotechnology for its potential use in catalysis and as a precursor to gold nanoparticles. Additionally, digold oxide has been studied for its potential use in gas sensors and in photoluminescent materials.Check Digit Verification of cas no
The CAS Registry Mumber 1303-57-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,0 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.Calculate Digit Verification of CAS Registry Number 1303-57:
(6*1)+(5*3)+(4*0)+(3*3)+(2*5)+(1*7)=47
47 % 10 = 7
So 1303-57-7 is a valid CAS Registry Number.
