Preparation
Cerium(III) hydroxide is obtained in industrial scale from monazide sand, (Ce, La, Th)PO4. In the laboratory, it may be prepared by treating caustic soda solution with cerium(III) chloride, followed by crystallization. CeCl3 + 3NaOH → Ce(OH)3 + NaCl.
Check Digit Verification of cas no
The CAS Registry Mumber 15785-09-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,7,8 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 15785-09:
(7*1)+(6*5)+(5*7)+(4*8)+(3*5)+(2*0)+(1*9)=128
128 % 10 = 8
So 15785-09-8 is a valid CAS Registry Number.
InChI:InChI=1/Ce.3H2O/h;3*1H2/q+3;;;/p-3
