Calculate Digit Verification of CAS Registry Number 79817-04:
(7*7)+(6*9)+(5*8)+(4*1)+(3*7)+(2*0)+(1*4)=172
172 % 10 = 2

Regioselective Alkylation of Anthrahydroquinone and Anthrone in Water with Quinonemethides and Other Alkylating Agents

Dimmel, Donald R.,Shepard, Donaline

, p. 22 - 29 (2007/10/02)

Antrahydroquinone (AHQ) and anthrone are alkylated in the C10 position by quinonemethides, generated in situ from p-acetoxybenzyl chlorides, to give adducts 13-15, 24, 25, 28, 29, and 32.Aqueous alkylations of AHQ with methyl vinyl ketone, cinnamaldehyde, and benzyl chloride also produces C10-substituted 10-hydroxyanthrones.Simple ketones and aldehydes do not, however, alkylate AHQ in aqueous alkali.
