Cuprite, a naturally occurring red or brownish mineral, is primarily composed of copper(I) oxide (Cu2O). It is an important ore of copper and is found in various parts of the world, including the United States, Chile, and Australia. Cuprite has a cubic crystal structure and is known for its distinctive red color, which is due to the presence of copper ions. The mineral is often associated with other copper minerals, such as chalcopyrite and bornite, and is typically found in hydrothermal veins and replacement deposits. Cuprite is an essential component in the production of copper, as it is processed to extract the valuable metal. Additionally, it has been used historically as a pigment in paints and ceramics, although its use has declined due to the development of more stable and less toxic alternatives.

Check Digit Verification of cas no

The CAS Registry Mumber 1308-76-5 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 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1308-76:
(6*1)+(5*3)+(4*0)+(3*8)+(2*7)+(1*6)=65
65 % 10 = 5
So 1308-76-5 is a valid CAS Registry Number.
