99328-47-9 Usage
General Description
Aluminum oxide (Al2O3), chromium-doped, is a compound that is formed by adding a small amount of chromium to aluminum oxide. This process produces a material with improved properties such as increased hardness, wear resistance, and thermal conductivity compared to pure aluminum oxide. Chromium-doped aluminum oxide is commonly used in the production of abrasives, ceramic materials, and refractory products due to its high strength and heat-resistant nature. Additionally, it is also utilized in the production of high-performance cutting tools, grinding wheels, and electrical insulators. The addition of chromium enhances the material's ability to withstand high temperatures and harsh environments, making it a valuable component in various industrial applications.
Check Digit Verification of cas no
The CAS Registry Mumber 99328-47-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,3,2 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99328-47:
(7*9)+(6*9)+(5*3)+(4*2)+(3*8)+(2*4)+(1*7)=179
179 % 10 = 9
So 99328-47-9 is a valid CAS Registry Number.
