Check Digit Verification of cas no

The CAS Registry Mumber 627869-64-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,7,8,6 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 627869-64:
(8*6)+(7*2)+(6*7)+(5*8)+(4*6)+(3*9)+(2*6)+(1*4)=211
211 % 10 = 1
So 627869-64-1 is a valid CAS Registry Number.

Synthesis of amino acids with unnatural nucleobases or chromophores suitable for use in model electron-transfer studies

Wagner, Thomas,Davis, William B.,Lorenz, Katrin B.,Michel-Beyerle, Maria E.,Diederichsen, Ulf

, p. 3673 - 3679 (2003)

We describe the syntheses of Boc-protected amino acids bearing the chromophores pyromellitic diimide, naphthalene diimide, and pyrene in their side chains, as well as nucleo amino acids with the artificial purines 7-carbaguanine, 7-carbaadenine, isoadenine, and 7-carbaisoadenine covalently linked to the alanyl side chain. These amino acids incorporating chromophores are suitable building blocks for incorporation into alanyl-PNA for future investigations of the mechanism of nucleobase-mediated electron transfer.
