Check Digit Verification of cas no

The CAS Registry Mumber 100188-03-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,1,8 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 100188-03:
(8*1)+(7*0)+(6*0)+(5*1)+(4*8)+(3*8)+(2*0)+(1*3)=72
72 % 10 = 2
So 100188-03-2 is a valid CAS Registry Number.

Synthesis of Naphthalenoferrocenophanes

Kasahara, Akira,Izumi, Taeko,Shimizu, Iwao,Oikawa, Tadashi,Umezawa, Hiroshi,et al.

, p. 1560 - 1569 (2007/10/02)

Several naphthalenoferrocenophanes, in which the two cyclopentadienyl rings are linked by two naphthalene rings were synthesized via intramolecular reductive coupling of the corresponding formyl compounds with a low valent titanium reagent.Their structures are deduced from IR, NMR, and UV spectra.Transannular ?-electronic interaction between the two naphthalene rings is discussed on the basis of electronic spectra.
