Check Digit Verification of cas no

The CAS Registry Mumber 220308-32-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,3,0 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 220308-32:
(8*2)+(7*2)+(6*0)+(5*3)+(4*0)+(3*8)+(2*3)+(1*2)=77
77 % 10 = 7
So 220308-32-7 is a valid CAS Registry Number.

Practical radical cyclisations leading to the construction of near-stereopure quaternary carbon stereogenic centres

McCague, Raymond,Pritchard, Robin G.,Stoodley, Richard J.,Williamson, Douglas S.

, p. 2691 - 2692 (1998)

The 2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl auxiliary is effective in directing bromopropargyloxy additions to the olefinic bonds of vinylogous esters/carbonates; in the presence of AIBN and 1-ethylpiperidinium hypophosphite, the adducts undergo highly stereoselective reductive radical cyclisations in which quaternary carbon stereogenic centres are generated.
