Check Digit Verification of cas no

The CAS Registry Mumber 1258865-89-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,8,6 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1258865-89:
(9*1)+(8*2)+(7*5)+(6*8)+(5*8)+(4*6)+(3*5)+(2*8)+(1*9)=212
212 % 10 = 2
So 1258865-89-2 is a valid CAS Registry Number.

Synthesis and structural analysis of a novel iodinated cyclopentadienone via ring-contraction iodination and its application in synthesis of alkyne-functionalized cyclopentadienones

scheme or table, p. 8171 - 8173 (2010/12/19)

The first iodinated cyclopentadienone was isolated and its structure was confirmed by single crystal X-ray analysis. Based on this intermediate, the first direct C-C bond formation on cyclopentadienone ring was achieved. The photo induced intramolecular charge transfer of alkynylated cyclopentadienones was evaluated by solvent polarity effect on their electronic absorption spectra.
