3119-88-8 Usage
Preparation
Preparation by reaction of 2-fluorobenzoyl chloride with resorcinol dimethyl ether in the presence of aluminium chloride in refluxing ethylene dichloride for 30 min (78%) or refluxing hexane for 8 h. Titanium tetrachloride can also be used instead of aluminium chloride.
Check Digit Verification of cas no
The CAS Registry Mumber 3119-88-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,1 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3119-88:
(6*3)+(5*1)+(4*1)+(3*9)+(2*8)+(1*8)=78
78 % 10 = 8
So 3119-88-8 is a valid CAS Registry Number.

BeCl2 as a new highly selective reagent for dealkylation of aryl-methyl ethers
Sharghi, Hashem,Tamaddon, Fatemeh
, p. 13623 - 13640 (2007/10/03)
An efficient and simple method is introduced for the selective removal of methyl group from poly aryl-methyl ethers, in some important derivatives of benzophenones, xanthones, anthraquinones, aryl esters, benzamides and nitroanisoles with BeCl2.
