95222-73-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 95222-73-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,2,2 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 95222-73:
(7*9)+(6*5)+(5*2)+(4*2)+(3*2)+(2*7)+(1*3)=134
134 % 10 = 4
So 95222-73-4 is a valid CAS Registry Number.

A novel three-component one-pot pyrimidine synthesis based upon a coupling-isomerization sequence

Muller, Thomas J. J.,Braun, Roland,Ansorge, Markus

, p. 1967 - 1970 (2000)

(Equation presented) 246-Tri(hetero)aryl-substituted pyrimidines can be readily synthesized in a three-component one-pot process based upon a coupling-isomerization sequence of an electron-poor (hetero)aryl halide and a terminal propargyl alcohol subseque

Facile synthesis of triarylpyrimidines with microwave-irradiated reactions of N-phenacylpyridinium chloride

Wu, Ping,Cai, Xi-Mei,Wang, Qi-Fang,Yan, Chao-Guo

, p. 223 - 229 (2007/10/03)

In a system of ammonium acetate and acetic acid under microwave irradiation, N-phenacylpyridinium chloride 1 reacted with 2 mol of aromatic aldehydes 2a-h to give 2,4,6-triarylpyrimidine 3a-h, reacted with pyridinecarboxaldehyde 4a-c and acetophenone 5 to yield bipyridine derivatives 6a-c. The structure of the products was characterized with 1H NMR, 13C NMR, IR, and mass spectroscopy. Copyright Taylor & Francis Group, LLC.
