Uses
L-Threonine tert-butyl ester is a protected form of L-Threonine (T405500). L-Threonine is an essential amino acid that is commonly used as a feed and food additive. L-Threonine is produced in mass quantities by mutant Escherichia coli strains for research and food nutrition purposes. L-Threonine can be naturally found in fish and poultry, and is incorporated in some important proteins in the human body (such as hemoglobin and insulin).
Check Digit Verification of cas no
The CAS Registry Mumber 69320-90-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,3,2 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69320-90:
(7*6)+(6*9)+(5*3)+(4*2)+(3*0)+(2*9)+(1*0)=137
137 % 10 = 7
So 69320-90-7 is a valid CAS Registry Number.

Total Synthesis of Seongsanamide B
Hutton, Craig A.,Shabani, Sadegh
, (2020)
The first total synthesis of the bicyclic depsipeptide natural product seongsanamide B is described. The successful approach employed solid-phase peptide synthesis of a core heptapeptide, incorporating on-resin esterification, followed by solution-phase macrolactamization and a late stage intramolecular Evans-Chan-Lam coupling to generate the biaryl ether of the isodityrosine unit.
