54279-13-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54279-13-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,2,7 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 54279-13:
(7*5)+(6*4)+(5*2)+(4*7)+(3*9)+(2*1)+(1*3)=129
129 % 10 = 9
So 54279-13-9 is a valid CAS Registry Number.

OXIDATION OF 2-INDOLINONES WITH COBALT(II) SCHIFF'S BASE COMPLEXES
Inada, Akira,Morita, Yutaka
, p. 2139 - 2142 (2007/10/02)
The oxidation of 2-indolinones (1) catalysed with cobalt(II) Schiff's base complexes gave isatins (2), O-aminoketones (3), 3-hydroxy-2-indolinones (4), and dimers (5).
