Check Digit Verification of cas no

The CAS Registry Mumber 82203-34-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,0 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 82203-34:
(7*8)+(6*2)+(5*2)+(4*0)+(3*3)+(2*3)+(1*4)=97
97 % 10 = 7

C20H18O4, Mr = 322.34, monoclinic, C2/c or Cc, a = 14.65(2), b = 11.21(2), c = 11.10(2) Angstroem, β = 106.6(1) deg, U = 1747.1 Angstroem3,Z = 4, Dm = 1.25, Dx = 1.26 Mg m-3, Cu Kα radiation, λ = 1.5418 Angstroem, R = 0.060 for 765 unique reflexions. The title compound decomposes in solution at a rate significantly greater than those of related peroxides: the molecular structure has been determined to explore possible steric reasons for this.
