General Description
Tricopper arsenide is a chemical compound composed of three copper atoms bonded to one arsenic atom. It has the chemical formula Cu3As and is a dense, metallic solid with a dark brown color. Tricopper arsenide is commonly used as a semiconductor material in various electronic devices, particularly in photovoltaic cells and thermoelectric generators. It has unique optical and electrical properties, making it suitable for applications in solar energy conversion and thermal energy harvesting. Additionally, tricopper arsenide has been studied for its potential use in catalytic and sensing applications due to its ability to facilitate chemical reactions and detect specific molecules. However, it should be handled with caution as it contains toxic arsenic and copper elements.
Check Digit Verification of cas no
The CAS Registry Mumber 12005-75-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,0 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 12005-75:
(7*1)+(6*2)+(5*0)+(4*0)+(3*5)+(2*7)+(1*5)=53
53 % 10 = 3
So 12005-75-3 is a valid CAS Registry Number.

We report the crystal structure and physical properties of two Ni5As3-based compounds RE2Ni5As3O2 (RE = Ce, Sm). The former exhibits structural phase transition from tetragonal (space group I4/mmm, 139) to orthorhombic (space group Immm, 71) symmetry at 230 K, while the latter undergoes a charge-density-wave-like structural distortion with abrupt change of Ni-As bond length. Both compounds show antiferromagnetic transitions due to RE3+ ions ordering at 4.4 and 3.4 K, accompanying with the large enhancement of Sommerfeld coefficients comparing to the nonmagnetic La analogue. Although the Cu substitution for Ni induces structural anomalies and suppression of structural transition like the behaviors in La/Pr/Nd analogues, the superconductivity is not observed in both Cu-doped RE2Ni5As3O2 (RE = Ce, Sm) above 0.25 K. Our structural refinements reveal that the lacking of superconductivity in RE2(Ni1-xCux)5As3O2 might relate to the anomalous increase of As height, h1.
