Check Digit Verification of cas no
The CAS Registry Mumber 5732-90-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,3 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5732-90:
(6*5)+(5*7)+(4*3)+(3*2)+(2*9)+(1*0)=101
101 % 10 = 1
So 5732-90-1 is a valid CAS Registry Number.

Novel Synthesis of Five- and Six-Membered Spiro γ-Lactones in Rigid Bicyclic Systems
Cannone, Persephone,Belanger, Denis,Lemay, Gilles

The reaction of bis(bromomagnesio)alkanes with bridged tricyclic endo- and exo-dicarboxylic anhydrides and their dihydro derivatives provides a general and versatile route to corresponding tricyclic spiro γ-butanolides.Futher extension of this methodology to the dianhydride of bicyclooctene showed appreciable regioselectivity.The subsequent transformation of spiro γ-lactones into 4-spiro-2-butenolides by retro-Diels-Alder reaction has provided a simple and convenient synthesis of these molecules.Proton and 13C NMR spectra are reported for most of the compounds.
