551772-78-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 551772-78-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,1,7,7 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 551772-78:
(8*5)+(7*5)+(6*1)+(5*7)+(4*7)+(3*2)+(2*7)+(1*8)=172
172 % 10 = 2
So 551772-78-2 is a valid CAS Registry Number.

Surfaces designed for charge reversal
Matthews, James R.,Tuncel, Doenues,Jacobs, Robert M. J.,Bain, Colin D.,Anderson, Harry L.
, p. 6428 - 6433 (2003)
We have created surfaces which switch from cationic at pH 5, by attaching aminodicarboxylic acid units to silica and gold substrates. Charge reversal was demonstrated by monitoring the adsorption of cationic dyes (methylene blue and
