28627-67-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28627-67-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,6,2 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 28627-67:
(7*2)+(6*8)+(5*6)+(4*2)+(3*7)+(2*6)+(1*7)=140
140 % 10 = 0
So 28627-67-0 is a valid CAS Registry Number.

The nitro anomaly and Bronsted βnuc values in SN2 reactions on chlorine

Eliad, Linoam,Hoz, Shmaryahu

, p. 540 - 543 (2007/10/03)

The kinetics of chlorine transfer reactions between N-chlorosuccinimide (NCS) and four carbon nucleophiles (the conjugated bases of phenyldinitromethane, Meldrum's acid, phenylmalononitrile and phenylnitro-methane) in water were determined. A plot of log k for the SN2 reactions vs the pKa of the first three conjugated acids of the nucleophiles gave a straight line with a slope (βnuc) of 1.8. The data point for the mononitro derivative, phenylnitromethane, deviates negatively from the line by 6.7 log units. This deviation is typical of proton transfer reactions and was recently shown to occur also in SN2 reactions on bromine. Copyright

One-Electron Reduction Potential and Ring Opening of the Succinimidyl Radical in Water

Lind, Johan,Jonsson, Mats,Eriksen, Trygve E.,Merenyi, Gabor,Eberson, Lennart

, p. 1610 - 1614 (2007/10/02)

By means of pulse radiolysis in water, N-chlorosuccinimide (SCl) was reduced in a one-electron step to yield the succinimidyl radicals, S*, via the intermediacy of the radical anion, SCl*-.The rate of ring opening of S* was measured to be 8 x 104 s-1.By equilibrium with Cl2*-/2Cl-, the one-electron reduction potential of S* was determined to be 2.22 +/- 0.02 V vs NHE.From this value and other data, the N-H bond strength in succinimide was calculated to be 118 +/- 3 kcal/mol.

Nucleophilic Catalysis of the Hydrolysis of Phenyl Acetates by the Succinimide Anion in Aqueous Solution

Huffman, Robert W.

, p. 3687 - 3691 (2007/10/02)

Kinetic studies were conducted on the disapperance of some phenyl acetates in aqueous solutions buffered by succinimide/succinimide anion at 30 deg C.The most reasonable mechanistic scheme, compatible with the data, is that shown in Scheme I involving nuc
