65109-81-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65109-81-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,1,0 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 65109-81:
(7*6)+(6*5)+(5*1)+(4*0)+(3*9)+(2*8)+(1*1)=121
121 % 10 = 1
So 65109-81-1 is a valid CAS Registry Number.

Fluorination Reactions with HF/THF Medium Solvolysis of N-Tosyl-O-Phenylhydroxylamine
Dolbier, William R.,Celewicz, Lech,Ohnishi, Keiichi
, p. 4929 - 4930 (2007/10/02)
Solvolysis of N-tosyl-O-phenylhydroxylamine in HF/THF leads to regiospecific formation of p-fluorophenol via umpolung strategy which induces nucleophilic aromatic fluorine/hydrogen substitution.
