720-42-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 720-42-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,2 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 720-42:
(5*7)+(4*2)+(3*0)+(2*4)+(1*2)=53
53 % 10 = 3
So 720-42-3 is a valid CAS Registry Number.

CHEMISTRY OF ORGANO HALOGENIC MOLECULES. PART XCIV. THE EFFECT OF FLUORINE ON PHOTOCHEMICAL CARBON-HALOGEN BOND CLEAVAGE IN Z AND E-1-FLUORO-2-HALO-1,2-DIPHENYLETHYLENES

Gregorcic, A.,Zupan, M.

, p. 163 - 172 (2007/10/02)

Irradiation of Z and E-1-fluoro-2-halo-1,2-diphenylethylenes at λ=253.7 nm gave Z and E-2-fluoro-1,2-diphenylethylene and 1,2-diphenylacetylene.The phototransformation depended on the geometry of the molecule, the halogen atom present, and the solvent used.Introduction of fluorine on the olefinic carbon atom in the β-position to a carbon-halogen bond increased the photocleavage compared to the unsubstituted substrate, and reduced the electron transfer from the caged radical-pair to cationic intermediates.Increased solvent polarity resulted in enhanced photocleavage of the carbon-halogen bond.
