1193687-84-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1193687-84-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,3,6,8 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1193687-84:
(9*1)+(8*1)+(7*9)+(6*3)+(5*6)+(4*8)+(3*7)+(2*8)+(1*4)=201
201 % 10 = 1
So 1193687-84-1 is a valid CAS Registry Number.

Photoisomerisation and ligand-controlled reversible aggregation of azobenzene-functionalised gold nanoparticles

K?hntopp, Anja,Dabrowski, Alexandra,Malicki, Michal,Temps, Friedrich

, p. 10105 - 10107 (2014)

The photochemical behaviour of functionalised gold nanoparticles (AuNPs) carrying azobenzenethiolate-alkylthiolate monolayers was investigated. Repeated trans-cis and cis-trans isomerisation cycles could be performed in all cases with high efficiency. Reversible photoinduced aggregation was observed when azothiolates with long alkyl spacers (≥C7) were combined with short (C5) alkylthiolate coligands. The choice of a coligand thus offers control over the aggregation properties of the nanoparticles. This journal is the Partner Organisations 2014.
