Check Digit Verification of cas no
The CAS Registry Mumber 3457-13-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,5 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3457-13:
(6*3)+(5*4)+(4*5)+(3*7)+(2*1)+(1*3)=84
84 % 10 = 4
So 3457-13-4 is a valid CAS Registry Number.

Synthese von 4-Alkoxy-2-hydroxyphenylketoximen als Metallextraktions-Reagenzien
Beger, J.,Binte, H.-J.,Brunne, L.,Neumann, R.
, p. 269 - 277 (2007/10/02)
The C-Acylation (Friedel-Crafts reaction) of resorcinol with aluminium chloride, the monoetherification in 4-position of the resulting 2,4-dihydroxyphenylketones, and the preparation of oximes (8, 9, 10, 11) from this ketones were investigated.The compounds obtained are characterized by elemental analysis, and the i.r., u.v. and 1H-n.m.r. spectra are discussed.Solubility data of some oximes are determined in water, octane and toluene.The extraction properties for copper-(II)-and iron-(III)-ions are measured by isotope methods in relation to the extragent structure, the extraction time and the pH-range.
