Chemical Properties
Different sources of media describe the Chemical Properties of 17218-47-2 differently. You can refer to the following data:
1. dark pink to pink purple crystalline powder or
2. Potassium hexafluoronickelate(IV) evolves oxygen from water but gives bright red
solutions in anhydrous hydrogen fluoride. Above 350° in vacuo it decomposes according to: 3K2NiF6 → 2K3NiF6+NiF2+F2
Check Digit Verification of cas no
The CAS Registry Mumber 17218-47-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,2,1 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 17218-47:
(7*1)+(6*7)+(5*2)+(4*1)+(3*8)+(2*4)+(1*7)=102
102 % 10 = 2
So 17218-47-2 is a valid CAS Registry Number.
