Check Digit Verification of cas no

The CAS Registry Mumber 217456-67-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,4,5 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 217456-67:
(8*2)+(7*1)+(6*7)+(5*4)+(4*5)+(3*6)+(2*6)+(1*7)=142
142 % 10 = 2
So 217456-67-2 is a valid CAS Registry Number.

Benzylic C-glycosides via the Ramberg-Backlund reaction

Belica, Peter S.,Franck, Richard W.

, p. 8225 - 8228 (1998)

Easily prepared thioglycosides are oxidized to the sulfone level and then are subjected to Ramberg-Backlund conditions, i.e. a base plus halogenating agent. The products are exo glycals which upon hydrogenation afford C-glycosides.
