127291-60-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127291-60-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,2,9 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 127291-60:
(8*1)+(7*2)+(6*7)+(5*2)+(4*9)+(3*1)+(2*6)+(1*0)=125
125 % 10 = 5
So 127291-60-5 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 (1989)
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.
