Check Digit Verification of cas no

The CAS Registry Mumber 7248-68-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,4 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7248-68:
(6*7)+(5*2)+(4*4)+(3*8)+(2*6)+(1*8)=112
112 % 10 = 2
So 7248-68-2 is a valid CAS Registry Number.

Synthesis and 13C FT NMR spectroscopy of furan-2,3-dione derivatives

Hnach, M.,Aycard, J. P.,Zineddine, H.

, p. 393 - 396 (2007/10/02)

Substituted furan-2,3-diones were obtained by condensation of oxalyl chloride with silyl enol ether of para-substituted acetophenones (R = H, CH3, OCH3, Cl, Br, F), propiophenone, 1-tetralone, 6-methoxytetralone and 1-benzosuberone.The spectroscopic data obtained from IR, UV, 1H and 13C NMR studies are quite similar whichever are the substituents. furan-2,3-dione / 1H and 13C NMR / UV and IR spectra
