Tungsten hexaiodide, with the chemical formula W(I6)3, is a compound consisting of tungsten and iodine. It is a dark red-brown, crystalline solid that is highly sensitive to light and moisture. Tungsten hexaiodide is a strong oxidizing agent and can be used in various applications, such as the production of iodine and iodine-containing compounds, as well as in the synthesis of other tungsten compounds. Due to its reactivity, it is essential to handle tungsten hexaiodide with caution and store it in a cool, dark, and dry environment to prevent decomposition and potential hazards.
The CAS Registry Mumber 33963-20-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,6 and 3 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 33963-20: (7*3)+(6*3)+(5*9)+(4*6)+(3*3)+(2*2)+(1*0)=121 121 % 10 = 1 So 33963-20-1 is a valid CAS Registry Number.
