Check Digit Verification of cas no

The CAS Registry Mumber 3976-48-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,7 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3976-48:
(6*3)+(5*9)+(4*7)+(3*6)+(2*4)+(1*8)=125
125 % 10 = 5
So 3976-48-5 is a valid CAS Registry Number.

Iridium-catalyzed reactions of ω-Arylalkanols to α,ω- Diarylalkanes

Obora, Yasushi,Anno, Yuka,Okamoto, Ryuhei,Matsu-Ura, Toyomi,Ishii, Yasutaka

, p. 8618 - 8622 (2011/11/11)

The long and the short of it: An atom-economical route to α,ω-diarylalkanes from ω-arylalkanols was achieved by a direct one-step method, or a sequential two-step method depending on the alkyl chain length. The reaction proceeded through the formation of β-methylhydroxy- α,ω-diarylalkanes by dehydrogenation/β-alkylation, followed by dehydrogenation/decarbonylation. Copyright

Conformational study of the higher [n.n]paracyclophanes: Evaluation as potential hosts for molecular halogens and benzenes

Mascal, Mark,Kerdelhue, Jean-Luc,Batsanov, Andrei S.,Begley, Michael J.

, p. 1141 - 1151 (2007/10/03)

A fundamental study of the conformations of [7.7]-, [8.8]-, [9.9]-, [11.11]- and octamethyl[8.8]-paracyclophanes in the solid state shows that the [odd.odd] members of the series possess parallel, symmetrically disposed benzene rings. A new genre of inclu
