398-49-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 398-49-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,9 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 398-49:
(5*3)+(4*9)+(3*8)+(2*4)+(1*9)=92
92 % 10 = 2
So 398-49-2 is a valid CAS Registry Number.

Determination of Hydroxyaromatic Compounds in Complexes Mixtures by Tandem Mass Spectrometry

Stach, Joachim,Zimmer, Dieter,Moeder, Monika,Herzschuh, Rainer

, p. 946 - 952 (2007/10/02)

Derivatization of alkylated hydroxyaromatics with N-methyl-bis(trifluoroacetamide) is used for a rapid screening for alkylated hydroxyaromatic compounds in complex mixtures by tandem mass spectrometry.Applications are based on a detailed investigation of the fragmentation reactions of derivatized alkylated phenols, 2,3-dihydroindenols, indenols, 1,2,3,4-tetrahydronaphthols and naphthols.As shown by daughter-ion mass spectra obtained in different field-free regions ofba BEQQ-instrument, the loss of CF3COOH, CF3CO radical or CF3COO radical, respectively, is common for the compounds studied and acn be used for their detection by means of neutral mass loss scans.
