Check Digit Verification of cas no
The CAS Registry Mumber 2511-22-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,1 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2511-22:
(6*2)+(5*5)+(4*1)+(3*1)+(2*2)+(1*2)=50
50 % 10 = 0
So 2511-22-0 is a valid CAS Registry Number.

The present invention provides anti-oxidant 3, 5 - di-tert-butyl - 4 - hydroxy-benzoic acid methyl ester, which belongs to the field of organic chemical synthesis. In this method the methanol is used as the esterification reaction of the raw material is used as a reaction solvent, in order to sodium methoxide or paratoluene sulfonic acid as catalyst, 3, 5 di-tert-butyl - 4 - hydroxy benzoic acid with methanol in order to 1.0: 2.0 - 1.0: 15.0 molar ratio, in the 60 - 80 °C reflow reaction for 8 - 14h after evaporate the solvent, solid first with sodium carbonate or sodium bicarbonate saturated solution washing, distilled water washing to neutral, filtering, drying, to get the pure product 3, 5 - di-tert-butyl - 4 - hydroxy-benzoic acid methyl ester compound. The process of the invention is simple, mild reaction conditions, which avoids the use of toxic solvents, the cost is reduced, while at the same time favorable to the environment; to obtain high yield, high purity, and has a good industrial application prospect.

The occurrence of 3-oxo-6-keto-cyclohexa-1,4-diene (p-quinoketene) during an esterification process
Badea, Florin,Costea, Ion,Velter, Ingrid,Simion, Alina,Simion, Cristian
, p. 95 - 98 (2007/10/03)
We succeeded in demonstrating the occurrence of a 3-oxo-6-keto-cyclohexa-1,4-diene (also called p-quinoketene) 5 during an esterification process of a p-hydroxy acyl chloride with a hindered phenol, in the presence of triethylamine.
