84474-47-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 84474-47-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,4,7 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 84474-47:
(7*8)+(6*4)+(5*4)+(4*7)+(3*4)+(2*4)+(1*7)=155
155 % 10 = 5
So 84474-47-5 is a valid CAS Registry Number.

Cyclopentadienylidenes, XVI. Condensation Reactions of Cycloheptapyrrol-6(2H)-one with Substituted Cyclopentadienes to Novel Pentadecaazafulvalenes

Seitz, Gunther,Olsen, Rolf A.,Kaempchen, Thomas

, p. 3756 - 3765 (2007/10/02)

Condensation of the cyclopentadienes 5, 12, and 14, activated by electron-attracting substituents, with cycloheptapyrrol-6(2H)-one 6 by heating in acetic anhydride yields deeply coloured, potentially dipolar 6?-10?-systems, the cyclopentadienylidene-cycloheptapyrroles 7, 13, and 15.Their constitutions are determined by 1H NMR; typical spectroscopic data, especially characteristics of the electronic spectra, are discussed.
