Calculate Digit Verification of CAS Registry Number 84757-48:
(7*8)+(6*4)+(5*7)+(4*5)+(3*7)+(2*4)+(1*8)=172
172 % 10 = 2
So 84757-48-2 is a valid CAS Registry Number.

Duff Reaction with Flavones: Formation of Homobiflavones

Mohan, Santosh Bala,Murti, V. V. S.

, p. 887 - 888 (2007/10/02)

Duff reaction with 5-hydroxy-7,8-dimethoxyflavone (I) gives 5,7-dihydroxy-6-formyl-8-methoxyflavone (II) and I(5),II(5)-dihydroxy-I(7),II(7),I(8),II(8)-tetramethoxy: II(6)homobiflavone (III).Similarly, 5-hydroxy-3,8,3',4',5'-pentamethoxyflavone (IV) gives the corresponding 6-aldehyde (V) and I(5),II(5)-dihydroxy-I(3,8,3',4',5'),II(3,8,3',4',5')-decamethoxyhomobiflavone (VI).
