33155-73-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33155-73-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,1,5 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 33155-73:
(7*3)+(6*3)+(5*1)+(4*5)+(3*5)+(2*7)+(1*3)=96
96 % 10 = 6
So 33155-73-6 is a valid CAS Registry Number.

Dry reaction under microwave: Condensation of sulfones with aldehydes of KF-alumina
Villemin,Ben Alloum
, p. 63 - 68 (2007/10/02)
Ethyl phenylsulfonylacetate(1), phenylsulfonylacetonitrile(2) and phenylsulfonylacetophenone(3) were condensated with aldehydes (a-d) into unsaturated sulfone without solvent in the presence of KF on alumina under microwave irradiation.
