Check Digit Verification of cas no
The CAS Registry Mumber 5449-42-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,4 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5449-42:
(6*5)+(5*4)+(4*4)+(3*9)+(2*4)+(1*2)=103
103 % 10 = 3
So 5449-42-3 is a valid CAS Registry Number.

Metal-free ring-opening of epoxides with potassium trifluoroborates
Roscales, Silvia,Csaky, Aurelio G.

The ring-opening of epoxides with potassium trifluoroborates proceeds smoothly in the presence of trifluoroacetic anhydride under metal-free conditions. The reactions are regioselective and afford a single diastereomer. Both electron-rich and electron-poor aryltrifluoroborates are tolerated.
