Check Digit Verification of cas no

The CAS Registry Mumber 36681-31-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,6,8 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 36681-31:
(7*3)+(6*6)+(5*6)+(4*8)+(3*1)+(2*3)+(1*1)=129
129 % 10 = 9
So 36681-31-9 is a valid CAS Registry Number.

Templating photodimerization of trans-cinnamic acid esters with a water-soluble Pd nanocage

Karthikeyan,Ramamurthy

, p. 452 - 458 (2007/10/03)

A water-soluble octahedral Pd nanocage acting as a reaction vessel templates the photodimerization of substituted trans-cinnamic acid methyl esters in water. Irradiation of the host-guest complexes of trans-cinnamic acid methyl esters with the Pd nanocage resulted in selective formation of a syn head-head dimer in addition to the corresponding cis isomer. These results suggest that the guest molecules are preoriented in a selective fashion with the hydrophilic ester group facing water and the hydrophobic aryl group tucked within the cavity of the host. Such an orientation occurs at the hydrophobic-hydrophilic interface between the nanocage exterior and interior. Weak intermolecular C-H-π and π-π interactions between the host and the guest(s) are likely to be responsible for the lack of mobility of the reactant olefins during their short excited-state lifetime.
