Check Digit Verification of cas no
The CAS Registry Mumber 114-63-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 114-63:
(5*1)+(4*1)+(3*4)+(2*6)+(1*3)=36
36 % 10 = 6
So 114-63-6 is a valid CAS Registry Number.

The improved Kolbe-Schmitt reaction using supercritical carbon dioxide
Iijima, Takayuki,Yamaguchi, Tatsuaki
, p. 5309 - 5311 (2007)
A comparative analysis of the reactions between sodium phenoxide and CO2 under the gaseous and supercritical conditions has demonstrated the preferential effect of supercritical conditions for promoting the reactivity of CO2. A significant increase in product yield was obtained in supercritical CO2 compared to reactions undertaken in gaseous CO2.
Effect of Polyether Linkages on the Carboxylation of Sodium Phenoxide
Sakakibara, Tsutomu,Haraguchi, Kazuyo
, p. 279 - 280 (1980)
In the carboxylation of sodium phenoxide under mild conditions, the crown compound or polyethers with three to five ether linkages caused carboxylation to give o- and p-hydroxybenzoic acids, but not ethers with one or two linkages.The chelation of sodium phenoxide with polyethers changed the formation ratio of isomers.
