52692-22-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52692-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,6,9 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 52692-22:
(7*5)+(6*2)+(5*6)+(4*9)+(3*2)+(2*2)+(1*2)=125
125 % 10 = 5

A Synthesis of Diphenylmethyl Ketones
Bunce, Richard A.,Dowdy, Eric D.
, p. 3007 - 3014 (2007/10/02)
The anion derived from diphenylmethane (2 eq.) reacts with carboxylic esters and anhydrides (1 eq.) to form diphenylmethyl ketones in 55-75percent purified yields.The procedure is one-step and permits the introduction of functionality incompatible with conditions used in earlier syntheses.
