Check Digit Verification of cas no
The CAS Registry Mumber 685862-28-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,5,8,6 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 685862-28:
(8*6)+(7*8)+(6*5)+(5*8)+(4*6)+(3*2)+(2*2)+(1*8)=216
216 % 10 = 6
So 685862-28-6 is a valid CAS Registry Number.

Synthesis and structural study of [2.n ](2,5)pyridinophanes

[2.n](2,5)Pyridinophanes possessing a cyclobutane ring and dioxaoligomethylene chain as tethers were efficiently prepared by intramolecular [2+2] photocycloaddition of vinylpyridine derivatives using a 400-W high-pressure mercury lamp through a Pyrex filter. They were of cis-configuration with respect to the cyclobutane ring, which was proved by the specific methine proton signals at δ 3.95-4.14. If the dioxaoligomethylene chain is short, the reaction affords only two exo,syn- and anti-isomers among three possible ones. On the other hand, if the chain is long enough, it gives three possible isomers interconverting at equilibrium. It is concluded that [2.n](2,5)pyridinophanes are rigid if n=4, 5 but flexible if n≥6.
