153782-93-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 153782-93-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,7,8 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 153782-93:
(8*1)+(7*5)+(6*3)+(5*7)+(4*8)+(3*2)+(2*9)+(1*3)=155
155 % 10 = 5
So 153782-93-5 is a valid CAS Registry Number.

A convenient synthesis of chiral N-Boc-amino ethers as potential peptide bond surrogate units
Ho, Mengfei,Chung, James K. K.,Tang, Nancy
, p. 6513 - 6516 (2007/10/02)
Boron triflouride etherate and zinc triflate have been found to be effective catalysists for the synthetic route to chiral N-Boc-amino ethers via a Lewis acid-catalyzed ring-opening of N-acyl aziridines, derived from chiral amino acids.
