174568-52-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 174568-52-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,5,6 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 174568-52:
(8*1)+(7*7)+(6*4)+(5*5)+(4*6)+(3*8)+(2*5)+(1*2)=166
166 % 10 = 6
So 174568-52-6 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.
