657-26-1 Usage
Uses
Synthesis of hyperbranched polylysine using the N-hydroxysuccinimide ester of L-lysine dihydrochloride as AB 2 building block. The histidine and lysine standards were prepared from L-histidine monohydro- chloride and L-lysine dihydrochloride respectively. L-Homocitrulline-The copper complex was prepared from L-lysine dihydrochloride in 80 to 86 per cent yields.
Purification Methods
Crystallise it from MeOH, in the presence of excess HCl, by adding diethyl ether. [Yoneya J Biochem (Tokyo) 38 343 1951, Kearley & Ingersoll J Am Chem Soc 73 5783 1951, Beilstein 4 IV 2717.]
Check Digit Verification of cas no
The CAS Registry Mumber 657-26-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,5 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 657-26:
(5*6)+(4*5)+(3*7)+(2*2)+(1*6)=81
81 % 10 = 1
So 657-26-1 is a valid CAS Registry Number.

The synthesis and application of three chiral receptors based on the covalent linkage of 1,1′-binaphthylphosphoric acids is reported. The binding of the lysine enantiomers to the chiral receptors was investigated by DOSY-NMR and NMR titrations, revealing that the bisphosphoric acid 1d acts as a highly stereoselective receptor for binding of d-lysine.
