Check Digit Verification of cas no

The CAS Registry Mumber 80403-83-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,0 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80403-83:
(7*8)+(6*0)+(5*4)+(4*0)+(3*3)+(2*8)+(1*3)=104
104 % 10 = 4
So 80403-83-4 is a valid CAS Registry Number.

SYNTHESIS OF 3-HALOISOXAZOLES BY NOVEL OXIDATIVE DEGRADATION OF THE SIDE-CHAIN OF 3-(3-HALO-ISOXAZOL-5-YL) PROPIONIC ACIDS

Lugosi, Peter,Schawartz, Jozsef,Doleschall, Gabor

, p. 3061 - 3066 (1981)

A novel method for the oxidative degradation of the side-chain of 3-(3-haloisoxazol-5-yl) propionic acids has been developed.The E-3-(3-chloroisoxazol-5-yl) propenoic acid 13a obtained by treatment of the s-triazolo quinazolin-4-ium iodide 11a with PhI(OAc)2 and Bz2O2, respectively, and subsequent hydroxysis, has been used for the synthesis of numerous 3-haloisoxazole derivatives.
