15520-84-0 Usage
Chemical Properties
green hygroscopic, reacts vigorously with organic solvents [KIR79]
Preparation
Anhydrous Co(NO3)3 can be prepared as green hygroscopic
crystals by the reaction of dinitrogen pentoxide on cobalt(III) fluoride.
Structure and conformation
It is volatile at fairly low temperatures (e.g. 40° and 10-2 mm Hg) and reacts vigorously with a range of organic solvents. A crystal structure determination shows the nitrate groups to be bidentate and the coordination around cobalt to be basically octahedral. All the Co-O bonds are equivalent, being 1.90±0.02 ?, but the O-Co-O angle for each bidentate ligand is only 68°.
Check Digit Verification of cas no
The CAS Registry Mumber 15520-84-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,5,2 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 15520-84:
(7*1)+(6*5)+(5*5)+(4*2)+(3*0)+(2*8)+(1*4)=90
90 % 10 = 0
So 15520-84-0 is a valid CAS Registry Number.
