Check Digit Verification of cas no

The CAS Registry Mumber 1228689-10-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,6,8 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1228689-10:
(9*1)+(8*2)+(7*2)+(6*8)+(5*6)+(4*8)+(3*9)+(2*1)+(1*0)=178
178 % 10 = 8
So 1228689-10-8 is a valid CAS Registry Number.

Anodic coupling reactions and the synthesis of C-glycosides

Xu, Guoxi,Moeller, Kevin D.

supporting information; experimental part, p. 2590 - 2593 (2010/08/22)

A convenient, two-step procedure has been developed for converting sugar derivatives into C-glycosides containing a masked aldehyde functional group. The chemistry takes advantage of an anodic coupling reaction between an electron-rich olefin and an alcohol. The sequence works for the formation of both furanose and pyranose derivatives if less polarized vinyl sulfide derived radical cation intermediates are used. With more polarized enol ether derived radical cations, the cyclizations work best for the formation of furanose derivatives where the rate of five-membered ring formation precludes elimination reactions triggered by the radical cation.
