Check Digit Verification of cas no

The CAS Registry Mumber 189875-68-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,8,7 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 189875-68:
(8*1)+(7*8)+(6*9)+(5*8)+(4*7)+(3*5)+(2*6)+(1*8)=221
221 % 10 = 1
So 189875-68-1 is a valid CAS Registry Number.

Synthesis characterizations and properties of a new fluoro-maleimide polymer

Mokhtar,Abd-Elaziz,Gomaa

, p. 616 - 620 (2010)

Novel 4-(4-trifluoromethyl)phenoxy N-phenyl-maleimide (FPMI) was synthesized. The free radical-initiated polymerization of FPMI was carried out in 1,4-dioxane solution using azobisisobutyronitrile as initiator. The monomer was investigated by FTIR, 1H NMR, 13C NMR and elemental analysis, while the polymer was investigated by FTIR, 1H NMR and 13C NMR. The effect of the monomer concentration, initiator concentration and temperature on the rate of polymerization (Rp) was studied. The activation energy of the polymerization was calculated (ΔE = 48.94 kJ/mol). The molecular weight of PFPMI (over(M, -)w and over(M, -)n) and polydispersity index of the polymer were determined by gel permeation chromatography and were equal to 73,500, 16,700 and 2.27, respectively. The properties of PFPMI, including thermal behavior, thermal stability, the glass transition temperature (Tg = 236 °C), photo-stability, solubility and solution viscosity were studied.
