78229-53-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78229-53-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,2,2 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 78229-53:
(7*7)+(6*8)+(5*2)+(4*2)+(3*9)+(2*5)+(1*3)=155
155 % 10 = 5
So 78229-53-5 is a valid CAS Registry Number.

Dispirocyclobutanes and Propellanes from 1,2-Bisenollactones

Kaup, Gerd,Schmitt, Dieter

, p. 1983 - 1990 (2007/10/02)

Electronically excited biphthalidylidene (1) and isocoumarino-isocoumarin (5) are trapped by electron-poor stilbenes and by 1,3-dienes to give the dispirocyclobutanes 3, 8, 9, 11, 12 and the heterocyclic propellanes 6 and 14, resp.The unusual tetraspirocyclobutane 4 is formed upon photodimerization of 1 as a by-product.The structures of the products have been established primarily by high-field 1H-NMR spectroscopy and in part by chemical transformations.
