Check Digit Verification of cas no

The CAS Registry Mumber 20217-29-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,1 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20217-29:
(7*2)+(6*0)+(5*2)+(4*1)+(3*7)+(2*2)+(1*9)=62
62 % 10 = 2
So 20217-29-2 is a valid CAS Registry Number.

(17)O-ENRICHED HYDROGEN PEROXIDE AND T.BUTYL HYDROPEROXIDE: SYNTHESIS, CHARACTERIZATION AND SOME APPLICATIONS

Barieux, J.J.,Schirmann, J.P.

, p. 6443 - 6446 (1987)

Solutions of (17)O-labelled hydrogen peroxide and t.butyl hydroperoxide in water or anhydrous solvents are easily obtained, starting from labelled oxygen.These stable enriched (17)O prducts are valuable reagents to synthesize various labelled molecules, which have been characterized by (17)O-NMR spectroscopy.Chemical shifts of several O-containing groups are given.
