Check Digit Verification of cas no
The CAS Registry Mumber 431-49-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 431-49:
(5*4)+(4*3)+(3*1)+(2*4)+(1*9)=52
52 % 10 = 2
So 431-49-2 is a valid CAS Registry Number.

Preparation of β,β-Difluoro-α-(trifluoromethyl)styrenes by Palladium-Catalyzed Coupling of Aryl Iodides with Pentafluoropropen-2-ylzinc Reagent
Morken, Peter A.,Burton, Donald J.

Substituted aromatic iodides are functionalized by pentafluoropropen-2-ylzinc, CF3C(ZnX)=CF2 (X = Br, I, or CF2=CCF3-), in the presence of Pd(PPh3)4 to give the corresponding arenes in good yields.This is particularly attractive for the preparation of title styrenes substituted with groups such as -NO2 or CO2R, which are incompatible with organomagnesium reagents.The best yields of the title styrenes with electron-donating substituents were obtained in DMF.For electron-withdrawing substituents, the best results were achieved in triglyme.A correlation was observed between Hammett ? constants and 19F NMR chemical shifts (R = 0.93-0.99, n = 8) and 2JF-F coupling constants (R = 0.94, n = 8).
