34238-86-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 34238-86-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,2,3 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 34238-86:
(7*3)+(6*4)+(5*2)+(4*3)+(3*8)+(2*8)+(1*6)=113
113 % 10 = 3
So 34238-86-3 is a valid CAS Registry Number.

Chiral aziridine ring opening: facile synthesis of (R)-mexiletine and (R)-phenoxybenzamine hydrochloride

Viswanadh,Velayudham,Jambu,Sasikumar,Muthukrishnan

, p. 5269 - 5271 (2015/08/26)

Abstract A simple and efficient synthesis of chiral drugs (R)-mexiletine 1, an anti-arrhythmic drug and (R)-phenoxybenzamine hydrochloride 2, an anti-hypertensive drug has been described via controlled reductive ring opening of chiral aziridine as a key step. The target compounds 1 and 2 were obtained in overall yields of 34% and 10.5%, respectively.

A facile enantioselective synthesis of enantiomerically pure (R)-phenoxybenzamine hydrochloride using the hydrolytic kinetic resolution method

Nikalje, Milind D.,Sasikumar, Murugesan,Muthukrishnan, Murugan

, p. 2825 - 2829 (2011/03/23)

A practical and highly efficient enantioselective synthesis of (R)-phenoxybenzamine hydrochloride has been described for the first time using Jacobsen's hydrolytic kinetic resolution of a terminal epoxide as a key step and source of chirality.
