Aluminum n-hexadecoxide, also known as aluminum oxide or alumina (Al2O3), is a chemical compound composed of aluminum and oxygen. It is a white, crystalline solid that occurs naturally as the mineral corundum and is also synthesized industrially. Aluminum oxide is widely used in various applications, including as a refractory material in furnaces, as an abrasive in sandpaper and grinding wheels, and as a catalyst in chemical reactions. It is also a key component in the production of aluminum metal and is used in the manufacturing of ceramics, glass, and electronics. Due to its high melting point, hardness, and electrical insulation properties, aluminum oxide is an important material in many industrial processes.

Check Digit Verification of cas no

The CAS Registry Mumber 6667-71-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,6 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6667-71:
(6*6)+(5*6)+(4*6)+(3*7)+(2*7)+(1*1)=126
126 % 10 = 6
So 6667-71-6 is a valid CAS Registry Number.
