1661-32-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1661-32-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,6 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1661-32:
(6*1)+(5*6)+(4*6)+(3*1)+(2*3)+(1*2)=71
71 % 10 = 1
So 1661-32-1 is a valid CAS Registry Number.

Isobenzofuran (IBF) precursor characterization using IR, NMR, X-ray and thermogravimetric analysis

Packe-Wirth,Enkelmann

, p. 1 - 9 (1998)

The Diels-Alder (DA) addition product of epoxynaphthalene with tetraphenylcyclopentadienone serves as a precursor for isobenzofuran (IBF), one of the most reactive dienes known. A detailed investigation on the DA reaction of epoxynaphthalene with tetraphenylcyclopentadienone shows, that in addition to the main, commonly described DA product [Fieser and Haddadin, J. Am. Chem Soc. 86 (1964) 208; Fieser and Hadddin, Can. J. Chem. 43 (1965) 1599], another stereoisomer by-product is formed. The two isomers are compared with respect to their thermal and spectroscopic properties. Spectroscopic investigations show that Fieser's assumed exo,exo-configuration for the main product is indead an exo,endo-configuration. The by-product turns out to be the exo,exo-stereoisomer.
