7605-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7605-40-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,0 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7605-40:
(6*7)+(5*6)+(4*0)+(3*5)+(2*4)+(1*0)=95
95 % 10 = 5
So 7605-40-5 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.
