N-trifluoroacetyl-leucylphenylalanine methylester (N-trifluoroacetyl-L-leucyl-L-phenylalanyl methyl ester) is a synthetic chemical compound with the molecular formula C16H18F3NO4. It is a derivative of the naturally occurring dipeptide leucylphenylalanine, where the N-terminus is acylated with a trifluoroacetyl group, and the C-terminus is esterified with a methyl group. N-trifluoroacetyl-leucylphenylalanine methylester is known for its potential applications in pharmaceutical research, particularly in the development of drugs targeting specific enzymes or receptors. Its unique structure, featuring the trifluoroacetyl group, may enhance its stability and bioactivity, making it a subject of interest in medicinal chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 859-45-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,5 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 859-45:
(5*8)+(4*5)+(3*9)+(2*4)+(1*5)=100
100 % 10 = 0
So 859-45-0 is a valid CAS Registry Number.

Racemisation-free Esterification of 2-Nitrophenylsulphenyl-protected Amino-acids by Dicyclohexylcarbodi-imide-4-Dimethylaminopyridine

Neises, Bernhard,Andries, Thomas,Steglich, Wolfgang

, p. 1132 - 1133 (2007/10/02)

Racemisation during esterification of N-protected amino-acids by dicyclohexylcarbodi-imide-4-dimethylaminopyridine (DDC-DMAP) can be avoided by use of the 2-nitrophenylsulphenyl (Nps) protecting group.
