Check Digit Verification of cas no

The CAS Registry Mumber 171411-70-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,4,1 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 171411-70:
(8*1)+(7*7)+(6*1)+(5*4)+(4*1)+(3*1)+(2*7)+(1*0)=104
104 % 10 = 4
So 171411-70-4 is a valid CAS Registry Number.

Template-directed intramolecular C-glycosidation. Formation of tetrahydrofurans and application to the synthesis of a higher-order sugar

Craig, Donald,Pennington, Mark W.,Warner, Peter

, p. 13495 - 13512 (2007/10/03)

Cation-mediated cyclisation reactions of silyl enol ether-containing thioglycosides give bicyclic ketotetrahydrofurans. Cyclisation of an analogous 3-phenyl-2-propenyl ether-containing substrate gives an intermediate in the total synthesis of the higher-order sugar 2,3-dideoxy-D- manno-2-octulopyranosonic acid.
