84019-44-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84019-44-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,0,1 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 84019-44:
(7*8)+(6*4)+(5*0)+(4*1)+(3*9)+(2*4)+(1*4)=123
123 % 10 = 3
So 84019-44-3 is a valid CAS Registry Number.

Synthesis of 4,7-Indolequinones by Photoinduced Reaction of Azidoquinones
Kozuka, Tadashi
, p. 2922 - 2927 (2007/10/02)
Various azidoquinones were prepared from methyl 3-substituted 2,3-dihydro-5-hydroxy-6-methylbenzofuran-2-carboxylate.Irradiation of these azidoquinones gave methyl 3-substituted 6-methyl-4,7-dioxoindole-2-carboxylates, a model of mitomycin analogs, in a moderate yield.
