80514-73-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80514-73-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,1 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80514-73:
(7*8)+(6*0)+(5*5)+(4*1)+(3*4)+(2*7)+(1*3)=114
114 % 10 = 4
So 80514-73-4 is a valid CAS Registry Number.

Efficient "One-Pot" Synthesis of N-Trityl Amino Acids
Barlos, Kleomenis,Papaioannou, Dionysios,Theodoropoulos, Dimitrios
, p. 1324 - 1326 (2007/10/02)
A sequential procedure has been developed whereby neutral amino acids 1 were tritylated via their corresponding trimethylsilyl esters 2 to afford, after mild hydrolysis, N-trityl amino acids 3 in high yields and purity.Hydroxy amino acids 4 were preferent
