50698-76-5 Usage
General Description
S-(carboxymethyl)-D-cysteine is a chemical compound that is a derivative of the amino acid cysteine. It is also known as N-acetyl-L-cysteine or NAC and is commonly used as a dietary supplement. It is known for its antioxidant properties and is commonly used to treat acetaminophen overdose and to help in the management of conditions such as chronic obstructive pulmonary disease (COPD) and cystic fibrosis. S-(carboxymethyl)-D-cysteine is also being studied for its potential benefits in treating psychiatric disorders, respiratory infections, and other health conditions. It may also have potential uses in improving liver function and detoxification.
Check Digit Verification of cas no
The CAS Registry Mumber 50698-76-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,6,9 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 50698-76:
(7*5)+(6*0)+(5*6)+(4*9)+(3*8)+(2*7)+(1*6)=145
145 % 10 = 5
So 50698-76-5 is a valid CAS Registry Number.

Optical Resolution of Racemic S-(Carboxymethyl)cysteine
Kleemann, Axel,Martens, Juergen
, p. 1995 - 1998 (2007/10/02)
Racemic S-(carboxymethyl)cysteine obtained from racemic cysteine is resolved via its ammonium salt (R,S)-3 by preferential crystallization procedure.Furthermore, (R,S)-2 forms with optically active amines separable, diastereomeric salts.Thus, (1R,2S)-2-amino-1-phenyl-1-propanol (4) affords optically pure (R)-S-(carboxymethyl)cysteine in 93 percent yield.The resolution of (R,S)-2 is also possible with (R)-1-phenylethylamine (5).
