Cuprous sulfide, also known as copper(I) sulfide, is a chemical compound with the formula Cu2S. It is a black solid that occurs naturally as the mineral chalcopyrite. Cuprous sulfide is a p-type semiconductor with a band gap of 1.2 eV, making it useful in various electronic applications, such as solar cells and photodetectors. It is also used as a pigment in ceramics and glass, as well as in the production of copper metal through the pyrometallurgical process. Due to its toxicity and potential environmental impact, handling and disposal of cuprous sulfide must be done with caution and in accordance with safety regulations.

1308-78-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1308-78-7 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 8 respectively; the second part has 2 digits, 7 and 8 respectively.Calculate Digit Verification of CAS Registry Number 1308-78:
(6*1)+(5*3)+(4*0)+(3*8)+(2*7)+(1*8)=67
67 % 10 = 7
So 1308-78-7 is a valid CAS Registry Number.
