Biochem/physiol Actions
L-cysteic acid is an oxidation product of L-cysteine. L-Cysteic acid, an analogue of cysteine sulfinic acid, may be used in studies of excitatory amino acids in the brain, such as those that bind to cysteine sulfinic acid receptors. L-Cysteic acid is a useful agonist at several rat metabotropic glutamate receptors (mGluRs).
Purification Methods
Likely impurities are cystine and oxides of cysteine. Crystallise it from water by adding 2 volumes of EtOH. When recrystallised from aqueous MeOH it has m 264-266o, and the anhydrous acid has m ~260o(dec).

Check Digit Verification of cas no
The CAS Registry Mumber 23537-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,5,3 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 23537-25:
(7*2)+(6*3)+(5*5)+(4*3)+(3*7)+(2*2)+(1*5)=99
99 % 10 = 9
So 23537-25-9 is a valid CAS Registry Number.
