126256-23-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126256-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,2,5 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 126256-23:
(8*1)+(7*2)+(6*6)+(5*2)+(4*5)+(3*6)+(2*2)+(1*3)=113
113 % 10 = 3
So 126256-23-3 is a valid CAS Registry Number.

Synthesis of β-Oxo Esters from Silyl Enol Ethers and Dichlorobis(phenoxy)methane
Mayr, Herbert,Cambanis, Anton,Baeuml, Englbert
, p. 1571 - 1573 (2007/10/02)
Dichlorobis(phenoxy)methane (1) reacts with trimethylsiloxyalkenes in the presence of 1.2 equiv. of TiCl4 to give β-oxo esters in 44-82percent yield.The title compound 1 is thus employed as a PhO2C+ equivalent.
