Check Digit Verification of cas no
The CAS Registry Mumber 91121-02-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,2 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91121-02:
(7*9)+(6*1)+(5*1)+(4*2)+(3*1)+(2*0)+(1*2)=87
87 % 10 = 7
So 91121-02-7 is a valid CAS Registry Number.

Dehydration Reactions with Gallic Acid Esters
Mayer, Walter,Hoffmann, Edmund H.,Loesch, Norbert,Wolf, Hans,Wolter, Burkhard,Schilling, Gerhard
, p. 929 - 938 (2007/10/02)
Gallic acid methylester (1) is oxidized by horseradish peroxidase giving the benzotropolone compound 3 and dimethyl 3,3',4,4',5,5'-hexahydro-2,2'-diphenate (2) which easily forms ellagic acid (4).By the analogous reaction with the gallic acid esters of ethanediol, 1,3-propanediol, 1,4-butanediol, trans-1,2-cyclohexanediol, 3,6-digalloylglucose, and pentagalloylglucose only 4 is formed.Oxidation of 1 by air in alkaline medium yields 4 and the 1-benzofuran derivative 9.If 9 is treated with alkali the furan ring is opened to give an intermediate from which the acconitic acid derivative 11 or the naphthalene system 12 or the benzoxepine compound 14 are obtained.By oxidation of 1 with iron(III)chloride the furan 15 is obtained.
