83638-63-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83638-63-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,6,3 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 83638-63:
(7*8)+(6*3)+(5*6)+(4*3)+(3*8)+(2*6)+(1*3)=155
155 % 10 = 5
So 83638-63-5 is a valid CAS Registry Number.

Reactions of 4-Hidroxycyclohexa-2,5-dienones under Acidic Conditions

Davis, Brian R.,Gash, Diana M.,Woodgate, Paul D.,Woodgate, Sheila D.

, p. 1499 - 1508 (2007/10/02)

The 4-hydroxy-4-phenyl-2,6-di-t-butylcyclohexa-2,5-dienone (2) undergoes reaction in acidic conditions to give, inter alia, derivatives of an arene-1,2-diol.In poorly nucleophilic media, the 1,1'-biphenyl-4-ol (16) and the 5-phenyl-o-benzoquinone (37) are the main products.Isolation of the 4-(2-methylpropyl)cyclohexadienone derivatives (41) and (42) provides the first examples of intermolecular trapping of a four-carbon unit.The products are consistent with the intervention of the phenoxenium ion (44); the formation of the 2-methyl-1,3-benzodioxole (43) testifies to the intermediacy of such a powerful oxidant.Whereas the 4- phenyl-2-t-butyl-p-quinol (5) gave a complex mixture from which only the 1,1'-biphenyl-4-ol derivative (24) was isolated, the 2,6-di-isopropyl- and 2,6-dimethyl-analogues (4) and (6) afforded mainly the arene-1,3-diol derivatives (48) and (47), respectively.The 4-methyl-2,6-di-t-butyl-p-quinol (7) gave products arising from nucleophilic attack on an intermediate p-quinone methide; dimers were the major products in the absence of a good nucleophile.
