22101-08-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 22101-08-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,0 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 22101-08:
(7*2)+(6*2)+(5*1)+(4*0)+(3*1)+(2*0)+(1*8)=42
42 % 10 = 2
So 22101-08-2 is a valid CAS Registry Number.

The acid-mediated ring opening reactions of α-aryl-lactams
King, Frank D.,Caddick, Stephen
, p. 3244 - 3252 (2012/06/01)
4-Aryl-azetidin-2-ones (β-lactams) undergo ring opening with triflic acid to give cinnamamides which, in benzene, react further to give 3-aryl-3-phenyl-propionamides. Prolonged reaction times in benzene give 3,3-diphenyl-propionamide via an aryl/phenyl ex
