Check Digit Verification of cas no

The CAS Registry Mumber 24123-12-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,1,2 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 24123-12:
(7*2)+(6*4)+(5*1)+(4*2)+(3*3)+(2*1)+(1*2)=64
64 % 10 = 4
So 24123-12-4 is a valid CAS Registry Number.

Synthesis of peptidinol adenylates

Kreimeyer, Annett,Marliere, Philippe

, p. 2339 - 2350 (2007/10/03)

Peptidinol adenylates were assembled by condensing the carboxyl group of N-blocked peptides with the alkylamino group of leucinol 5' adenosine phosphodiester. The latter was prepared as protected precursor from adenosine and leucinol by phosphite chemistry. The title compounds, which mimic aminoacyl adenylates, are designed to penetrate microorganisms via peptide permeases and to interfere with genetic translation.
