10294-62-9 Usage
Chemical Properties
hexagonal prisms; decomposes at white heat; refractive index 1.564 (20°C) [HAW93] [MER06]
Physical properties
White hexagonal crystals; density 2.82 g/cm3; slightly soluble in cold water, solubility decreasing with temperature; insoluble in ethanol; dehydrates in the air at 400°C.
Uses
Lanthanum sulfate is used to prepare many lanthanum compounds.
Preparation
Lanthanum sulfate is prepared by dissolving lanthanum oxide, hydroxide or carbonate in sulfuric acid, followed by crystallization. La2O3 + 3H2SO4 → La2(SO4)3 + H2O La2(CO3)3 + 3H2SO4 → La2(SO4)3 + 3CO2 + 3H2O.
Check Digit Verification of cas no
The CAS Registry Mumber 10294-62-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,9 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 10294-62:
(7*1)+(6*0)+(5*2)+(4*9)+(3*4)+(2*6)+(1*2)=79
79 % 10 = 9
So 10294-62-9 is a valid CAS Registry Number.
