Purification Methods
Recrystallise the acid chloride from *C6H6. If it is not very pure (presence of OH or NH bands in the IR), dissolve it in pyridine, shake it with phosgene in toluene, evaporate and recrystallise the residue. Carry out this experiment in a good fume cupboard as COCl2 is very TOXIC, and store the product in the dark. It is moisture sensitive. The amide has m 246.5-247o, and the dimethylaminoethylamide hydrochloride has m 197-198o. [Weston et al. J Am Chem Soc 75 4006 1953, Beilstein 20 III/IV 3841.]
Check Digit Verification of cas no
The CAS Registry Mumber 73500-82-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,5,0 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73500-82:
(7*7)+(6*3)+(5*5)+(4*0)+(3*0)+(2*8)+(1*2)=110
110 % 10 = 0
So 73500-82-0 is a valid CAS Registry Number.

A USEFUL REAGENT FOR DERIVATIZATION OF AMINO ACIDS
Allenmark, Stig
, p. 1455 - 1458 (1990)
N-(Chloroformyl)-carbazole, which is readily synthesized by phosgenation of carbazole, has been shown to be an excellent reagent for fluorogenic labelling of amino acids.The derivatization reaction is carried out at room temperature in a borate buffer of pH 9 and yields highly fluorescent derivatives with good chromatographic properites.Further, the derivatives of amino acid enantiomers are well separated on BSA-silica (Resolvosil) analytical columns.
