Check Digit Verification of cas no
The CAS Registry Mumber 20790-76-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,9 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20790-76:
(7*2)+(6*0)+(5*7)+(4*9)+(3*0)+(2*7)+(1*6)=105
105 % 10 = 5
So 20790-76-5 is a valid CAS Registry Number.

The C3-N Bond Cleavage of 2-Amino-3-(N-substituted-amino)propionic Acids Catalyzed by L-Methionine γ-Lyase

L-Methionine γ-lyase (EC 4.4.1.11) catalyzes α,β-elimination of L-2-amino-3-(N-methylamino)propionic acid and L-2-amino-3-(N-hydroxyethylamino)propionic acid to yield pyruvate, ammonia, and the corresponding amines.These amino acids also undergo the enzymatic β-replacament reaction with thiols to produce the corresponding S-substituted cysteines.Thus, L-methionine γ-lyase cleaves a C-N bond in addition to C-S, C-Se, and C-O bonds at the β position of amino acids by elimination and replacement reactions.A linear relationship between the reactivity, (log(Vmax/Km) and the pKa value of the conjugated acid of the leaving group has been found for Se-methyl-L-selenocysteine, S-methyl-L-cysteine, and O-methyl-L-serine.However, L-2-amino-3-(N-methylamino)propionic acid has shown lower reactivity than that expected from the pKa value of methylammonium ions.
