1252-04-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1252-04-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,5 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1252-04:
(6*1)+(5*2)+(4*5)+(3*2)+(2*0)+(1*4)=46
46 % 10 = 6
So 1252-04-6 is a valid CAS Registry Number.

Determination of enantiomeric purity of commercial 14C- and 3H- labeled L-α-amino acids

LeFevre, Joseph W.,Bonzagni, Neil J.,Chappell, Lara L.,Clement, David J.,Albro, Jeb R.,Lezynski, Denise M.

, p. 477 - 489 (2007/10/03)

The enantiomeric purity of twelve commercial 14C- and 3H-labeled L- α-amino acids was determined using reverse isotope dilution analysis. The technique utilized reversed-phase (RP) thin-layer chromatography (TLC) and beta-cyclodextrin (β-CD) in the mobile phase to separate D- and L-amino acids as their 5-dimethylamino-1-naphthalene sulfonyl (dansyl, DNS) derivatives. In all cases, the L-amino acid was contaminated with the D- isomer. This is the first report of the resolution of N-DNS-DL-tyrosine and N-(α)-DNS-DL-lysine using this methodology.
