42497-90-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42497-90-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,4,9 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 42497-90:
(7*4)+(6*2)+(5*4)+(4*9)+(3*7)+(2*9)+(1*0)=135
135 % 10 = 5
So 42497-90-5 is a valid CAS Registry Number.

A Protocol to Transform Sulfones into Nitrones and Aldehydes

Rodrigo, Eduardo,Alonso, Inés,Cid, M. Belén

supporting information, p. 5789 - 5793 (2018/09/29)

A simple method to transform sulfones into nitrones and therefore into the corresponding carbonyl derivatives has been developed. Some examples demonstrate that it is a new reliable and versatile reaction in the toolbox of sulfones that has great synthetic potential. NMR and computational studies were used to elucidate the mechanism.
