Check Digit Verification of cas no

The CAS Registry Mumber 1233718-78-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,7,1 and 8 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1233718-78:
(9*1)+(8*2)+(7*3)+(6*3)+(5*7)+(4*1)+(3*8)+(2*7)+(1*8)=149
149 % 10 = 9
So 1233718-78-9 is a valid CAS Registry Number.

Copper oxide nanoparticles catalyzed vinylation of imidazoles with vinyl halides under ligand-free conditions

Prakash Reddy,Vijay Kumar,Rama Rao

experimental part, p. 3181 - 3185 (2010/08/05)

Recyclable copper oxide nanoparticles catalyzed most efficient and straightforward protocol for the vinylation of imidazoles with vinyl halides under ligand-free conditions. Utilizing this protocol various imidazoles were cross-coupled with different substituted vinyl halides to get the corresponding products in excellent yields with the retention configuration.
