Calculate Digit Verification of CAS Registry Number 109002-49:
(8*1)+(7*0)+(6*9)+(5*0)+(4*0)+(3*2)+(2*4)+(1*9)=85
85 % 10 = 5
So 109002-49-5 is a valid CAS Registry Number.

3-OXO-INDAZOLINE AND 4-OXO-DIHYDROQUINAZOLINE DERIVATIVES FROM ISATIC ACIDS

Alemagna, A.,Baldoli, C.,Licandro, E.,Maiorana, S.,Papagni, A.

, p. 5397 - 5402 (1986)

The coupling of diazonium salts from isatic acids with alkoxycarbonylmethylenephosphoranes leads directly to 3-oxo-indazolin-2-yl-(alkoxycarbonyl)methylenetriphenylphosphoranes, while coupling with methyl 2-chloroacetacetate gives 2-phenyl-glyoxylic acid.
