Check Digit Verification of cas no
The CAS Registry Mumber 160622-41-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,6,2 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 160622-41:
(8*1)+(7*6)+(6*0)+(5*6)+(4*2)+(3*2)+(2*4)+(1*1)=103
103 % 10 = 3
So 160622-41-3 is a valid CAS Registry Number.

Synthesis of 2- and 4-oxo-1H-1-azaanthracene-9,10-diones from 2-amino-1,4-naphthoquinone
Marcos, Alicia,Pedregal, Carmen,Avendano, Carmen
, p. 12941 - 12952 (2007/10/02)
In spite of the poor nucleophilicity of its amino group, which is considered to have an "amide like" character, 2-amino-1,4-naphthoquinone reacts with β-dielectrophiles to give 2-oxo- or 4-oxo-1H-1-azaanthracene-9,10-diones.
