11039-68-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 11039-68-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,1,0,3 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 11039-68:
(7*1)+(6*1)+(5*0)+(4*3)+(3*9)+(2*6)+(1*8)=72
72 % 10 = 2
So 11039-68-2 is a valid CAS Registry Number.

Research ArticlesDetermination of Phenoxymethyl penicilloic acid (cas 11039-68-2) and Phenoxyethyl penicilloic acid (cas 11039-68-2) in Urine in the Presence of the Parent Penicillins08/21/2019

Penicillin and the corresponding penicilloic acid are extracted by chloroform from an acidified sample of urine which has been partly saturated by ammonium sulfate. A portion of the extract is dried and redissolved in a small volume of acetone. A measured aliquot is chromatographed on a silica g...detailed

Analytical MethodsLabel-free surface-enhanced Raman scattering strategy for rapid detection of penicilloic acid (cas 11039-68-2) in milk products08/19/2019

A label-free surface-enhanced Raman scattering (SERS) strategy based on silver-coated gold nanoparticles ([email protected] NPs) was developed for rapid detection of penicilloic acid (PA) in milk products. It has been demonstrated that core size and shell thickness of [email protected] NPs are t...detailed

Molecularly imprinted polymer cartridges coupled to liquid chromatography for simple and selective analysis of penicilloic acid (cas 11039-68-2) and penilloic acid in milk by matrix solid-phase dispersion08/18/2019

A simple, fast and sensitive method for determination of the degradation products of penicillin (penicilloic acid and penilloic acid) in milk samples has been developed by combining selective surface molecularly imprinted matrix solid-phase dispersion and high performance liquid chromatography (...detailed

Structure-selective hot-spot Raman enhancement for direct identification and detection of trace penicilloic acid (cas 11039-68-2) allergen in penicillin08/17/2019

Trace penicilloic acid allergen frequently leads to various fatal immune responses to many patients, but it is still a challenge to directly discriminate and detect its residue in penicillin by a chemosensing way. Here, we report that silver-coated gold nanoparticles ([email protected] NPs) exhi...detailed

Utility of surface enhanced Raman spectroscopy (SERS) for elucidation and simultaneous determination of some penicillins and penicilloic acid (cas 11039-68-2) using hydroxylamine silver nanoparticles08/16/2019

Elucidation and quantitative determination of some of commonly used penicillins (ampicillin, penicillin G and carbenicillin) in the presence of their main degradation product (penicilloic acid) were developed. Forced acidic and basic degradation processes were applied at different time intervals...detailed
