Biochem/physiol Actions
DL-Cysteine is a racemic mixture of the proteinogenic amino acids L-cysteine and the non-proteinogenic D-cysteine. DL-Cysteine is used as an organic reagent and in comparative physicochemical analysis of processes such as crystallization.
Purification Methods
Crystallise the salt from hot 20% HCl and dry it under vacuum over P2O5. It also crystallises from EtOH with m 175o (hydrate). When crystallised from absolute EtOH or EtOH/Et2O, it has m 140-141.5o (anhydrous). [Rurner & Voitle J Am Chem Soc 72 628 1950, Albert Biochem J 50 690 1953, Beilstein 4 IV 3145.]
Check Digit Verification of cas no
The CAS Registry Mumber 10318-18-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,3,1 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 10318-18:
(7*1)+(6*0)+(5*3)+(4*1)+(3*8)+(2*1)+(1*8)=60
60 % 10 = 0
So 10318-18-0 is a valid CAS Registry Number.
