Check Digit Verification of cas no

The CAS Registry Mumber 10524-20-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,5,2 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 10524-20:
(7*1)+(6*0)+(5*5)+(4*2)+(3*4)+(2*2)+(1*0)=56
56 % 10 = 6
So 10524-20-6 is a valid CAS Registry Number.

Manganese(III)-Mediated γ-Lactone Annulation

Fristad, William E.,Peterson, John R.

, p. 10 - 18 (2007/10/02)

The annulation of a γ-lactone ring onto an alkene by manganese(III) acetate oxidation of acetic acid was investigated.The regioselectivity of addition to unsymmetrically substituted alkenes is reported along with the stereoselectivity of addition to various acyclic and cyclic alkenes.Alkenes with ionization potentials above 8.2 eV were found to react in good yield.The role of acetic anhydride in these reactions was studied, and it was shown to be oxidized faster than acetic acid and also led to different products.The fate of oxidized acetic acid or anhydridein the absence of suitable acceptor molecule has also been quantitatively identified.The relationship of enolizability, or C-H acidity, of the carboxylic acid being oxidized was established quantitatively.
