103582-39-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 103582-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,5,8 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 103582-39:
(8*1)+(7*0)+(6*3)+(5*5)+(4*8)+(3*2)+(2*3)+(1*9)=104
104 % 10 = 4
So 103582-39-4 is a valid CAS Registry Number.

Synthesis, Spectral Data and Extraction of Copper by 1-(2'-Hydroxy-5'-alkylphenyl)-1-alkanone Oximes

Krzyzanowska, Ewa,Olszanowski, A.,Juskowiak, M.

, p. 617 - 630 (2007/10/02)

1-(2'-Hydroxy-5'-alkylphenyl)-1-ethanone oximes with a normal alkyl group containing 2 to 12 carbon atoms and 1-(2'-hydroxy-5'-methylphenyl)-1-alkanone oximes containing 1 to 11 carbon atoms in the hydrocarbon chain were synthesized.Spectral data (u.v., i.r., n.m.r. and 13C) of oximes are reported.Four of these oximes were used for copper extraction from acidic solution.The results obtained indicate, that these oximes are better extractants than alkyl derivatives of 2-hydroxybenzophenone oximes.
