Check Digit Verification of cas no

The CAS Registry Mumber 87831-99-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,8,3 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 87831-99:
(7*8)+(6*7)+(5*8)+(4*3)+(3*1)+(2*9)+(1*9)=180
180 % 10 = 0
So 87831-99-0 is a valid CAS Registry Number.

Development of a H3PW12O40/CeO2 catalyst for bulk ring-opening polymerization of a cyclic carbonate

Honda, Masayoshi,Abe, Hideki

, p. 4995 - 5006 (2018/11/10)

A new reaction system involving a heterogeneous H3PW12O40/CeO2 catalyst and methyl iodide initiator was developed for bulk ring-opening polymerization (ROP) of trimethylene carbonate (TMC). Combination of a Br?nsted acid (H3PW12O40) and Lewis base (CeO2) had a synergic effect on a well-controlled ROP without decarboxylation, which gave poly(TMC) of molecular weight (Mn) 30-000 and Polydispersity Index (PDI) of 1.80 at 60 °C and 24 h. Fourier transform infrared (FTIR) spectroscopy elucidated a reaction mechanism in which H3PW12O40 promoted the initiation reaction and CeO2 activated TMC, and the interface of these two components was an active site for ROP. The catalyst was removed readily by filtrating a dimethyl carbonate solution of poly(TMC), which was confirmed by inductively coupled plasma-atomic emission spectroscopy. In addition, various kinds of biomass-derived poly(aliphatic carbonate)s were synthesized and thermal properties were investigated by differential scanning calorimetry and thermogravimetry-differential thermal analysis. In particular, pyrolysis-gas chromatography mass spectrometry of these polymers revealed that the degradation mechanism was highly dependent upon a small amount of ether linkages and a pendant methyl group.

Direct cyclic carbonate synthesis from CO2 and diol over carboxylation/hydration cascade catalyst of CeO2 with 2-cyanopyridine

Honda, Masayoshi,Tamura, Masazumi,Nakao, Kenji,Suzuki, Kimihito,Nakagawa, Yoshinao,Tomishige, Keiichi

, p. 1893 - 1896 (2014/06/24)

We first achieved direct synthesis of propylene carbonate from CO 2 and 1,2-propanediol in excellent yield (>99%) using a carboxylation/hydration cascade catalyst of CeO2 with 2-cyanopyridine. The catalyst system can be applied to syntheses of various cyclic carbonates, including 6-membered ring carbonates that are difficult to synthesize in high yields (62->99%).

A novel and efficient method for the catalytic direct oxidative carbonylation of 1,2- and 1,3-diols to 5-membered and 6-membered cyclic carbonates

Gabriele, Bartolo,Mancuso, Raffaella,Salerno, Giuseppe,Ruffolo, Giuseppe,Costa, Mirco,Dibenedetto, Angela

experimental part, p. 7330 - 7332 (2010/02/28)

In the presence of a PdI2-based catalytic system, 1,2-diols undergo an oxidative carbonylation process to afford 5-membered cyclic carbonates in good to excellent yields (84-94%) and with unprecedented catalytic efficiencies for this kind of reaction (up to ca. 190 mol of product per mol of PdI2). Under similar conditions, 6-membered cyclic carbonates are obtained for the first time through a direct catalytic oxidative carbonylation of 1,3-diols (66-74% yields).
