42833-51-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 42833-51-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,8,3 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 42833-51:
(7*4)+(6*2)+(5*8)+(4*3)+(3*3)+(2*5)+(1*1)=112
112 % 10 = 2
So 42833-51-2 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.
