144369-52-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144369-52-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,3,6 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 144369-52:
(8*1)+(7*4)+(6*4)+(5*3)+(4*6)+(3*9)+(2*5)+(1*2)=138
138 % 10 = 8
So 144369-52-8 is a valid CAS Registry Number.

Syntheses and lipophilicities of tetraarylborate ions substituted with many trifluoromethyl groups

Fujiki, Kanji,Kashiwagi, Mitsuyoshi,Miyamoto, Hideyuki,Sonoda, Akinari,Ichikawa, Junji,et al.

, p. 307 - 321 (1992)

Syntheses were investigated using various tetraarylborate ions with a large number of trifluoromethyl groups: tetrakisborate; tetrakisborate; tetrakisborate; and tetrakisborate ions.The preparation of Grignard reagents and the subsequent reaction with boron trifluoride etherate are importantsteps for a higher yield and easier isolation of the product.Sodium- and tetramethylammonium salts of these borate ions are soluble in halocarbon solvents such as dichloromethane, chloroform and 1,2-dibromotetrafluoroethane.
