113330-88-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113330-88-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,3,3 and 0 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 113330-88:
(8*1)+(7*1)+(6*3)+(5*3)+(4*3)+(3*0)+(2*8)+(1*8)=84
84 % 10 = 4
So 113330-88-4 is a valid CAS Registry Number.

3-Arylidene derivatives of 3H-furan-2-ones. Synthesis and reaction with maleic anhydride
Egorova,Reshetov,Morozova,Sedavkina
, p. 910 - 913 (1997)
The synthesis of 5-alkyl(aryl)-3-arylidene-3H-furan-2-ones was accomplished, and their reaction with maleic anhydride was studied. The configuration, of the initial arylidene derivatives was established on the basis of the PMR spectra of the adducts obtai
