60566-20-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 60566-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,5,6 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 60566-20:
(7*6)+(6*0)+(5*5)+(4*6)+(3*6)+(2*2)+(1*0)=113
113 % 10 = 3
So 60566-20-3 is a valid CAS Registry Number.

Synthesis, antileishmanial activity and structure-activity relationship of 1-N-X-phenyl-3-N′-Y-phenyl-benzamidines

Rodrigues-Santos, Cláudio Eduardo,Leon, Leonor L.,Bortoluzzi, Adailton J.,Canto-Cavalheiro, Marilene Marcuzzo,Machado, Gérzia C.,Echevarria, Aurea

, p. 166 - 174 (2013/10/01)

Two series of N,N′-diphenyl-benzamidines were synthesized as part of a study to search potential new drugs with antileishmanial activity. These compounds were obtained by anilides in PCl5 halogenation reaction with generation in situ of the cor

Synthesis of Amides and Amidines by Reaction of Carboxylic Acids and Amines in the Presence of Polyphophoric Acid Trimethylsilyl Ester (PPSSE)

Ogata, Shin-ichi,Mochizuki, Amane,Kakimoto, Masa-aki,Imai, Yoshio

, p. 2171 - 2178 (2007/10/02)

The reaction between amines and carboxylic acids in the presence of poliphosphoric acid trimethylsilylester (PPSE) has been investigated from the view point of the synthesis of amides and amidines.Benzanilide was selectively prepared from benzoic acid and aniline in the presence of PPSE and pyridine at 100 degC, whereas a mixture of benzanilide and N,N'-diphenylbenzamidine was obtained without the use of pyridine.The reaction at 160 degC almost exclusively gave N,N'-diphenylbenzamidine.Various simmetrical amidines were obtained from combinations of carboxylic acids and aromatic amines in high yields by simply heating at 160 degC with four molar amounts of PPSE.The reactions of aliphatic and aromatic amines with N-monosubstituted and N,N-disubstituted amides also afforded corresponding unsymmetrical amidines under the same conditions.The reaction mechanism is discussed in some detail.
