125415-08-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125415-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,4,1 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 125415-08:
(8*1)+(7*2)+(6*5)+(5*4)+(4*1)+(3*5)+(2*0)+(1*8)=99
99 % 10 = 9
So 125415-08-9 is a valid CAS Registry Number.

SYNTHESIS OF 2-ARYL-3-CINNOLINONES BY CYCLISATION OF DIARYLAZO COMPOUNDS
Hutchings, Michael G.,Devonald, David P.
, p. 3715 - 3718 (2007/10/02)
Cyclisation of 2-arylazophenylacetic acid with oxalyl chloride gives novel 2-aryl-3-cinnolinones in good yield.Mixed ketene acetals derived from the corresponding phenylacetate esters also give the same product, sometimes with 2-arylindazoles, on treatmen
