Uses
Different sources of media describe the Uses of 13590-82-4 differently. You can refer to the following data:
1. calibrated against sodium oxalate, traceable to NIST SRM
2. Cerium(IV) sulfate is a redox indicator and is used in analytical chemistry for redox titrations. In ionized form, ceric ion acts as a strong oxidizer under acidic conditions. It is also used to prepare spherical-like nanoparticles CeO2, nanoparticles for NO reductions' reactions.
Preparation
Cerium(IV) sulfate is prepared by heating cerium(IV) oxide, CeO2 with concentrated H2SO4. Also it may be obtained by the reaction of H2SO4 with cerium carbonate: Ce(CO3)2 + 2H2SO4 + H2O → Ce(SO4)2?4H2O + 2CO2.

Check Digit Verification of cas no
The CAS Registry Mumber 13590-82-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,9 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13590-82:
(7*1)+(6*3)+(5*5)+(4*9)+(3*0)+(2*8)+(1*2)=104
104 % 10 = 4
So 13590-82-4 is a valid CAS Registry Number.
