General Description
Uranium disulphide, also known as US2, is a chemical compound composed of uranium and sulphur. It is a black, crystalline solid that is insoluble in water and has a high melting point. Uranium disulphide is primarily used as a precursor for the synthesis of other uranium compounds, and is also studied for its potential applications in nuclear energy and advanced materials. Due to its radioactive properties, uranium disulphide is handled with care to prevent exposure to harmful radiation. It is classified as a hazardous material and requires special handling and disposal procedures to ensure safety and minimize environmental impact.
Check Digit Verification of cas no
The CAS Registry Mumber 12039-14-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,3 and 9 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 12039-14:
(7*1)+(6*2)+(5*0)+(4*3)+(3*9)+(2*1)+(1*4)=64
64 % 10 = 4
So 12039-14-4 is a valid CAS Registry Number.

Complex Topologies from Simple Building Blocks: Uranium(IV) Thiophosphates
Klepov, Vladislav V.,Zur Loye, Hans-Conrad
, p. 11175 - 11183 (2018)
Six new uranium thiophosphates, Cs5Na6[U(PS4)4](PS4) (1), Rb5Na3[U(PS4)4] (2), CsNa[U(PS4)2] (3), Cs1.67Na0.52I0.19[U(PS4)2] (4), Cs1.033Na1.343I0.376[U(PS4)2] (5), and Rb1.35Na0.93I0.28[U(PS4)2] (6), were obtained from halide flux reactions and characterized using single-crystal X-ray diffraction. The structures of these compounds consist of a pseudotetrahedral uranium unit that in combination with a set of PS4 group coordination modes can result in an isolated [U(PS4)4]8- unit, a [U(PS4)2]2- chain, or a [U(PS4)2]2- slab. Optical and magnetic properties of 3 and 4 were collected. Both compounds exhibit paramagnetic behavior, and CsNa[U(PS4)2] (3) exhibits a magnetic transition at 200-225 K between two paramagnetic states that both have similar effective magnetic moments of 4.13 and 4.19 μB/formula unit, and strong antiferromagnetic interactions with θ = -183 and -172 K, for the high- and low-temperature states, respectively.
