51594-34-4 Usage
General Description
(1S,2S)-(+)-2-AMINO-3-METHOXY-1-PHENYL-1-PROPANOL, also known as Pseudoephedrine, is a chemical compound that belongs to the class of amines. It is widely used as a decongestant to relieve nasal and sinus congestion caused by various conditions such as the common cold, allergies, and hay fever. Pseudoephedrine works by narrowing the blood vessels in the nasal passages, which reduces swelling and congestion. Additionally, it also acts as a central nervous system stimulant, increasing blood pressure and heart rate. However,
Check Digit Verification of cas no
The CAS Registry Mumber 51594-34-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,5,9 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 51594-34:
(7*5)+(6*1)+(5*5)+(4*9)+(3*4)+(2*3)+(1*4)=124
124 % 10 = 4
So 51594-34-4 is a valid CAS Registry Number.

Asymmetric Synthesis of 2-Substituted Butyrolactones and Valerolactones
Meyers, A. I.,Yamamoto, Yukio,Mihelich, Edward D.,Bell, Richard A.
, p. 2792 - 2796 (2007/10/02)
The use of chiral oxazolines 1, 2, 5, and 8 under asymmetrically induced alkylation conditions gave α-substituted oxazolines 3, 6, 9, and 13 which were hydrolyzed to α-substituted butyro- and valerolactones 4 and 11.Either enantiomer of the lactones could be prepared in predictable absolute configuration by reversing the order of alkyl group introduction.The lactones were prepared in 60-86 percent enantiomeric excess which was determined by either chemical correlation or high-pressure liquid chromatography of the diastereomers 10.
