89635-72-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89635-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,3 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89635-72:
(7*8)+(6*9)+(5*6)+(4*3)+(3*5)+(2*7)+(1*2)=183
183 % 10 = 3
So 89635-72-3 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.
