Calculate Digit Verification of CAS Registry Number 1026148-81:
(9*1)+(8*0)+(7*2)+(6*6)+(5*1)+(4*4)+(3*8)+(2*8)+(1*1)=121
121 % 10 = 1
So 1026148-81-1 is a valid CAS Registry Number.

Solventless synthesis of 2,4,1 Oa-triaryl-1,1 Oadihydro-2H-pyrazino[2,1-b] [1,3] benzoxazole

Ravindran,Muthusubramanian,Selvaraj,Perumal

, p. 1047 - 1050 (2008/09/18)

A solventless synthesis of 2,4,10a-triaryl-1,10a-dihydro-2H-pyrazino[2,1-6] [1,3] benzoxazole has been achieved in good yield by the reaction of 2-[(2-oxo-2-arylethyl) anilino]-1-aryl-1-ethanones with 2-aminophenol in p-toluenesulfonic acid. The products have been characterized by 1H and 13C NMR spectroscopy.
