Calculate Digit Verification of CAS Registry Number 25993-83:
(7*2)+(6*5)+(5*9)+(4*9)+(3*3)+(2*8)+(1*3)=153
153 % 10 = 3
So 25993-83-3 is a valid CAS Registry Number.

A new and concise way to enamides by fluoroalkanosulfonyl fluoride mediated Beckmann rearrangement of α,β-unsaturated ketoximes

Yan, Zhaohua,Xu, Yun,Tian, Weisheng

supporting information, p. 7186 - 7189 (2015/02/02)

The reaction of α,β-unsaturated ketoximes with fluoroalkanosulfonyl fluorides in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) underwent the Beckmann rearrangement smoothly to afford the corresponding acid-sensitive enamides in moderate to excellent yields, which provides a new efficient method for the preparation of acid-sensitive enamides.
