333382-85-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 333382-85-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,3,3,8 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 333382-85:
(8*3)+(7*3)+(6*3)+(5*3)+(4*8)+(3*2)+(2*8)+(1*5)=137
137 % 10 = 7
So 333382-85-7 is a valid CAS Registry Number.

Synthesis of pyridinocrownophanes exhibiting high Ag+-affinity

Inokuma, Seiichi,Kimura, Koichi,Funaki, Takashi,Nishimura, Jun

, p. 123 - 130 (2007/10/03)

Crownophanes possessing a pyridine moiety were prepared by means of intramolecular [2 + 2] photocycloaddition of the styrene derivatives. The crown compounds having six to ten ethereal oxygens selectively extracted Ag+ with high efficiency in the liquid-liquid extraction. The high extractability and efficiency were maintained even at low pH region of the extraction system. From ESI-MS analysis, it was found that the crownophanes formed some kinds of complexes having 1:1 and 2:1 stoichiometry (host/guest) with Ag+ and Pb2+ in MeCN-H2O homogeneous system.
