67055-68-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67055-68-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,0,5 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 67055-68:
(7*6)+(6*7)+(5*0)+(4*5)+(3*5)+(2*6)+(1*8)=139
139 % 10 = 9
So 67055-68-9 is a valid CAS Registry Number.

Process for preparing butyl-p-benzoylbenzoates
-
, (2008/06/13)
Butyl-p-benzoylbenzoates are prepared by reacting a 4-(trichloromethyl) benzophenone with a butanol in the presence of an acid catalyst. These butyl-p-benzoylbenzoates are valuable photoinitiators for the polymerization of ethylenically unsaturated monomers.
