Check Digit Verification of cas no
The CAS Registry Mumber 320-62-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,2 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 320-62:
(5*3)+(4*2)+(3*0)+(2*6)+(1*2)=37
37 % 10 = 7
So 320-62-7 is a valid CAS Registry Number.

Deoxyfluorination of Carboxylic, Sulfonic, Phosphinic Acids and Phosphine Oxides by Perfluoroalkyl Ether Carboxylic Acids Featuring CF2O Units

The deoxyfluorination of carboxylic, sulfonic, phosphinic acids and phosphine oxides is a fundamentally important approach to access acyl fluorides, sulfonyl fluorides and phosphoric fluorides, thus the development of inexpensive, stable, easy-to-handle, versatile, and efficient deoxyfluorination reagents is highly desired. Herein, we report the use of potassium salts of perfluoroalkyl ether carboxylic acids (PFECA) featuring CF2O units as deoxyfluorination reagents, which are generated mainly as by-products in the manufacture of hexafluoropropene oxide (HFPO). The synthesis of acyl fluorides, sulfonyl fluorides and phosphoric fluorides can be realized via carbonic difluoride (COF2) generated in situ from thermal degradation of the PFECA salt.
