55520-93-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 55520-93-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,5,2 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 55520-93:
(7*5)+(6*5)+(5*5)+(4*2)+(3*0)+(2*9)+(1*3)=119
119 % 10 = 9
So 55520-93-9 is a valid CAS Registry Number.

Partition coefficients of ketones, phenols, aliphatic and aromatic acids, and esters in n-hexane/nitromethane

Kotowska, Urszula,Isidorov, Valery A.

scheme or table, p. 813 - 824 (2012/03/27)

Liquid-liquid partition is used in sample preparation and in countercurrent and liquid-liquid chromatographic separations. Partition coefficients are widely used in toxicology, environmental, and analytical chemistry. The K hn determination procedure for the n-hexane/ nitromethane system was optimized and partition coefficients for 99 ketones, esters and trimethylsilyl derivatives of phenols, aliphatic and aromatic acids were determined. For 130 compounds, Khn values were predicted using mathematical relationships between Khn and other physicochemical and structural parameters. Versita Sp. z o.o.
