Check Digit Verification of cas no
The CAS Registry Mumber 57244-54-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,2,4 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 57244-54:
(7*5)+(6*7)+(5*2)+(4*4)+(3*4)+(2*5)+(1*4)=129
129 % 10 = 9
So 57244-54-9 is a valid CAS Registry Number.

Selective Indirect Oxidation of Phenol to Hydroquinone and Catechol

The introduction of a hydroxyl function into phenol to give hydroquinone and catechol can be achieved in high yields by the reaction of hydrogen peroxide with alkenylphenols.These alkenylphenols are obtained by thermolysis of bisphenol A, alkylation of phenol with cyclopentadiene followed by isomerization, and alkylation of phenol with mesityl oxide followed by thermolysis to give 4-isopropenylphenol, 2- and 4-(cyclopenten-1-yl)phenol, and 2,2,4-trimethyl-1,2-chromene, respectively.
