799-87-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 799-87-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,9 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 799-87:
(5*7)+(4*9)+(3*9)+(2*8)+(1*7)=121
121 % 10 = 1
So 799-87-1 is a valid CAS Registry Number.

Design of experiments on the transesterification of tris(p-nitrophenyl) phosphate with sodium methoxide

Seiceira, Rafael C.,Nakayama, Hatumi T.,Costa Neto, Claudio,Cajaiba Da Silva, Joao F.,Pedrosa, Marcelo S.

, p. 389 - 395 (2007/10/03)

A design of experiments was conducted to study the transesterification of tris(p-nitrophenyl) phosphate with sodium methoxide. The factorial design was performed to check the experimental conditions that favored ths yield of bis(p-nitrophenyl) methyl phosphate in a semi-batch process. The experiments were performed using a Mettler RC1 calorimeter. The reaction temperature, the addition order of reagents and the time spent in those additions were analyzed at two different levels. The results showed the addition order of reagents as the most important factor to guarantee the improvement of the reaction yielding bis(p-nitrophenyl) methyl phosphate. It was demonstrated that the temperature has a small effect on the reaction yield between 5 and 30°C. An important effect was observed with regard to the addition time of reagents and yield: when the tris(p-nitrophenyl)phosphate is added to the methoxide solution (58% on average) while no effect was observed when the methoxide solution was added to the phosphate (87% on average). Theses results indicated that the addition could be made in times shorter than five minutes under the latter condition. Copyright Taylor & Francis Inc.

Solvent isotope effects as a probe of general catalysis and solvation in phosphoryl transfer

Bryan,Schowen,Schowen

, p. 931 - 938 (2007/10/03)

Phosphoryl transfer to methanol from PNNN, PMNN, and PMMN exhibits general base catalysis by acetate ion but no detectable catalysis by acetic acid. For PNNN, acetate catalysis produces normal solvent isotope effects that arise from a one-proton catalytic bridge in the transition state. The proton inventory for the least reactive substrate PMMN is suggestive of transition-state stabilization, while the proton inventory for the most reactive substrate PNNN suggests only generalized transition-state solvation. Furthermore, the proton inventory for PMNN suggests an intermediate situation. The data are consistent with a model in which transition states with exterior concentrations of charge favor stabilization of the charge by isotope-fractionating one-proton bridges, while transition states with distributed charge favor stabilization of the charge by many distributed sites.
