838825-87-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 838825-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,8,8,2 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 838825-87:
(8*8)+(7*3)+(6*8)+(5*8)+(4*2)+(3*5)+(2*8)+(1*7)=219
219 % 10 = 9
So 838825-87-9 is a valid CAS Registry Number.

Anion recognition and redox sensing by a metalloporphyrin-ferrocene- alkylammonium conjugate

Bucher, Christophe,Devillers, Charles H.,Moutet, Jean-Claude,Royal, Guy,Saint-Aman, Eric

, p. 1584 - 1589 (2004)

The synthesis and characterization of a novel redox molecular receptor is reported. This chemosensor is structured on a ferrocene fragment whose cyclopentadienyl moieties have been connected to distinct and complementary zinc porphyrin and alkylammonium binding sites, enabling multipoint recognition and detection of anionic species. Cumulative effects of multiple anchoring points on this ammonium-ferrocene-metalloporphyrin chemosensor allowed the unprecedented ferrocene-based voltammetric sensing of halide anions.
