Check Digit Verification of cas no
The CAS Registry Mumber 66056-60-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,0,5 and 6 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 66056-60:
(7*6)+(6*6)+(5*0)+(4*5)+(3*6)+(2*6)+(1*0)=128
128 % 10 = 8
So 66056-60-8 is a valid CAS Registry Number.

1,3-Dipolar cycloaddition route to nitrogen heterocyclic triones
Jones, Raymond C. F.,Bhalay, Gurdip,Carter, Paul A.,Duller, Kathryn A. M.,Dunn, Stephen H.
, p. 765 - 776 (2007/10/03)
1,3-Dipolar cycloaddition of nitrile oxides, formed in situ by dehydration of primary nitro compounds, with pyrrolidine enamines of protected γ- or δ-amino-β-keto esters affords isoxazole-4-carboxylates; these undergo lactam formation and N-O bond cleavage to afford 3-acyltetramic acids and 3-acyl-4-hydroxypyridin-2-ones.
