Check Digit Verification of cas no

The CAS Registry Mumber 156632-08-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,6,3 and 2 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 156632-08:
(8*1)+(7*5)+(6*6)+(5*6)+(4*3)+(3*2)+(2*0)+(1*8)=135
135 % 10 = 5
So 156632-08-5 is a valid CAS Registry Number.

Synthesis, lipophilicity studies and antibacterial properties of some novel quaternary ammonium salts

Siatra-Papastaikoudi,Papadaki-Valiraki,Tsantili-Kakoulidou,Tzouvelekis,Mentis

, p. 392 - 394 (1994)

The synthesis of some novel quaternary ammonium salts, derivatives of 15- phenyl-decapentanoic acid, is described. Their lipophilicity was estimated applying the Hansch-Leo fragmental procedure and measured by means of reversed phase thin layer chromatography. All compounds were tested for their antibacterial activity against Gram positive and gram negative microorganisms. The less lipophilic compounds showed weak activity, mainly against gram positive microorganisms.
