2-[(1S)-1-Aminoethyl]-5-fluorophenol is an ortho-hydroxybenzylamine obtained from the chiral phosphoric acid-catalyzed enantioselective transfer hydrogenation of ortho-Hydroxyaryl Alkyl N-H Ketimines.
Check Digit Verification of cas no
The CAS Registry Mumber 1228542-70-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,5,4 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1228542-70:
(9*1)+(8*2)+(7*2)+(6*8)+(5*5)+(4*4)+(3*2)+(2*7)+(1*0)=148
148 % 10 = 8
So 1228542-70-8 is a valid CAS Registry Number.

The first enantioselective chiral phosphoric acid-catalyzed transfer hydrogenation of unprotected ortho-hydroxyaryl alkyl N - H ketimines using Hantszch di-tert-butyl ester as a reductant is reported. A variety of ortho-hydroxybenzylamines were obtained in good to excellent yields and enantiomeric excesses.
