Check Digit Verification of cas no
The CAS Registry Mumber 4767-03-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,6 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4767-03:
(6*4)+(5*7)+(4*6)+(3*7)+(2*0)+(1*3)=107
107 % 10 = 7
So 4767-03-7 is a valid CAS Registry Number.

Kinetics of the electrocatalytic oxidation of 2,2-dimethylolpropionaldehyde
Liang, Zhenhai,Sun, Hongyan
, p. 47 - 56 (2009)
A new method of synthesis 2,2-dimethylolpropionic acid from 2,2-dimethylolpropionaldehyde was put forward. The electrochemical oxidation behavior of 2,2-dimethylolpropionaldehyde has been investigated on a Ti/SnO 2 + Sb2O4/PbO2 electrode by cyclic voltammetry (CV) and stable polarization curves in sulfuric acid. The results showed that it was an irreversible reaction controlled by diffusion. The formation mechanism of 2,2-dimethylolpropionic acid in the sulfuric acid was then proposed and the transfer coefficients of the reaction were calculated. It was concluded that RCHO+OHads→RCHOOHads was the rate-determining step in the electrolysis process. The rate of this step obtained from the assumed process agrees well with experiment.

, (2008/06/13)
A process for isolating polymethylolalkanoic acids or monomethylolalkanoic acids of the formula (I) where R are identical or different and are each a substituted or unsubstituted hydrocarbon radical or a methylol group, which have been prepared from the corresponding polymethylolalkanals or monomethylolalkanals of the formula (II) where R are as defined above, by oxidation using an aqueous solution of hydrogen peroxide comprises a) carrying out a crystallization followed by a liquid/solid separation (B) to give the acid as first crystallized material (2a) plus mother liquor (3), b) producing further crystallized material (2b) in the mother liquor (3) and separating the resulting mother liquor (3) from the further crystallized material (2b) in a further solid/liquid separation (C), and c) disposing of the resulting mother liquor (3) which has been depleted in the acid.
