Check Digit Verification of cas no
The CAS Registry Mumber 589-97-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,8 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 589-97:
(5*5)+(4*8)+(3*9)+(2*9)+(1*7)=109
109 % 10 = 9
So 589-97-9 is a valid CAS Registry Number.

Crystal structure of K2[C2O6] - First proof of existence and constitution of a peroxodicarbonate ion
Dinnebier, Robert E.,Vensky, Sascha,Stephens, Peter W.,Jansen, Martin
, p. 1922 - 1924 (2007/10/03)
By using high-resolution X-ray powder diffraction, we have determined the first crystal structure of a peroxodicarbonate compound, synthesized by electrocrystallization at -20°C. The constitution of the peroxodicarbonate anion was established and all structural details, including its conformation (see picture), can be understood qualitatively in terms of classical concepts of the chemical bond.
