Check Digit Verification of cas no

The CAS Registry Mumber 1959-48-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,5 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1959-48:
(6*1)+(5*9)+(4*5)+(3*9)+(2*4)+(1*8)=114
114 % 10 = 4
So 1959-48-4 is a valid CAS Registry Number.

PHOTOCHEMISTRY OF ORGANOHALOGENO-COMPOUNDS. PART XIX THE EFFECT OF FLUORINE ON PHOTOCHEMICAL CARBON-HALOGEN BOND CLEAVAGE

Gregorcic, A.,Zupan, M.

, p. 313 - 322 (1987)

Irradiation of 1,1-diphenyl-2-fluoro-2-haloethenes at λ = 253.7 nm gave 1,1-diphenyl-2-fluoroethene and the rearranged product trans-fluorostilbene.The phototransformation depended on the halogen present and the solvent used.Introduction of fluorine on th

A facile and mild method for the synthesis of terminal bromofluoroolefins via diethylzinc-promoted wittig reaction

Lei, Xinsheng,Dutheuil, Guillaume,Pannecoucke, Xavier,Quirion, Jean-Charles

, p. 2101 - 2104 (2007/10/03)

Synthesis of 1-bromo-1-fluoroolefins was achieved in good yields via a Wittig reaction promoted by diethylzinc, even with nonactivated aldehydes and ketones as starting materials.

Low-temperature 19F NMR spectroscopy of 1-fluoro-1-lithioethenes - Stability, shifts and unexpected coupling constants

Kvicala, Jaroslav,Hrabal, Richard,Czernek, Jiri,Bartosova, Ivana,Paleta, Oldrich,Pelter, Andrew

, p. 211 - 218 (2007/10/03)

Half-lives and fluorine atom shifts of stabilized 1-fluoro-l-lithioethenes bearing hydrogen, fluorine, phenyl, and/or dimethylphenylsilyl groups in the β-positions have been determined by a low-temperature 19F NMR spectroscopy. Some 1-fluoro-1-lithioethenes displayed an exceptionally low value of the trans-3JFF coupling constant. Stereoselectivity of carbenoid formation, as well as an effect of configuration on the stability is discussed.
