Check Digit Verification of cas no

The CAS Registry Mumber 221680-02-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,6,8 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 221680-02:
(8*2)+(7*2)+(6*1)+(5*6)+(4*8)+(3*0)+(2*0)+(1*2)=100
100 % 10 = 0
So 221680-02-0 is a valid CAS Registry Number.

NMR structural and kinetic assignment of fluoro-3H-naphthopyran photomerocyanines

Delbaere,Micheau,Teral,Bochu,Campredon,Vermeersch

, p. 694 - 699 (2007/10/03)

The kinetic and structural behavior of a photochromic compound, 3-(2-fluorophenyl)-3-phenyl-3H-naphtho[2,1-b]pyran (F-Py), was investigated using 1H and 19F nuclear magnetic resonance (NMR) spectroscopy. Upon irradiation, the four th

Complete assignment of the 1H, 13C and 19F NMR spectra of fluoro-substituted 3H-naphthopyrans

Delbaere, Stephanie,Teral, Yannick,Bochu, Christophe,Campredon, Mylene,Vermeersch, Gaston

, p. 159 - 162 (2007/10/03)

The complete assignment of the 1H, 13C and 19F NMR spectra of eight fluoro-substituted 3H-naphthopyrans was achieved by the concerted application of homonuclear (1H-1H) and heteronuclear (13C-1H and 19F-1H) correlations. Copyright
