Check Digit Verification of cas no
The CAS Registry Mumber 91624-89-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,2 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91624-89:
(7*9)+(6*1)+(5*6)+(4*2)+(3*4)+(2*8)+(1*9)=144
144 % 10 = 4
So 91624-89-4 is a valid CAS Registry Number.

Fluorine Magnetic Resonance Studies. VI. Fluorine-Fluorine Coupling Over Four Bonds in α-Fluoro- and α,α-Difluoro-toluenes

The 4J fluorine-fluorine coupling over four bonds involving an sp3 carbon and two sp2 carbons has been studied by using constrained structures to calibrate the dependence of the size of coupling on the dihedral angle (θ).Both CF and CF2 groups follow the pattern established for CF3, with the largest couplings (38, 62 and 86 Hz respectively) arising from closest approaches of two fluorines (θ = 0 deg) and the zero couplings resulting from θ = 180 deg.
