General Description
Ammonium praseodymium(3+) disulphate is a chemical compound consisting of ammonium cations and praseodymium(3+) ions coordinated with disulphate anions. It is a rare earth compound that is used in various industrial and scientific applications, such as catalysis, electronics, and metallurgy. The compound is a source of praseodymium, a rare earth metal that is valued for its magnetic, electrical, and optical properties. Ammonium praseodymium(3+) disulphate is typically produced through the reaction of praseodymium oxide with sulfuric acid and ammonium sulfate, resulting in a green crystalline solid that is soluble in water. Its specific chemical and physical properties make it a valuable resource for a range of technological and industrial processes.Check Digit Verification of cas no
The CAS Registry Mumber 21995-33-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,9 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.Calculate Digit Verification of CAS Registry Number 21995-33:
(7*2)+(6*1)+(5*9)+(4*9)+(3*5)+(2*3)+(1*3)=125
125 % 10 = 5
So 21995-33-5 is a valid CAS Registry Number.
