646-55-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 646-55-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 646-55:
(5*6)+(4*4)+(3*6)+(2*5)+(1*5)=79
79 % 10 = 9
So 646-55-9 is a valid CAS Registry Number.

Difluoroalkylamines from high temperature vapor phase reactions of nitrogen trifluoride with alkanes, ethers and benzene

Belter, Randolph K.

scheme or table, p. 961 - 964 (2011/11/06)

At temperatures around 400 °C, nitrogen trifluoride (NF3) readily reacts with alkanes and benzene as well as ethers. In all cases, products were N,N-difluoroamines. This is in contrast to difluoroamination of benzylic substrates where the initial N,N-difluoroamines underwent eliminations or rearrangements and were not isolated. Cyclic and acyclic alkanes generated N,N-difluoroaminoalkanes. Benzene substituted on the ring to form N,N-difluoroaniline. Ethers reacted to generate α-N,N-difluoroamino ethers. Little direct fluorination was observed.
