Check Digit Verification of cas no

The CAS Registry Mumber 206125-07-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,1,2 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 206125-07:
(8*2)+(7*0)+(6*6)+(5*1)+(4*2)+(3*5)+(2*0)+(1*7)=87
87 % 10 = 7
So 206125-07-7 is a valid CAS Registry Number.

Endocyclic cleavage of glycosides. VI. Substituent effects of the alkylative endocyclic cleavage of glycosides

Olsson, Roger,Berg, Ulf,Frejd, Torbjoern

, p. 3935 - 3954 (2007/10/03)

A number of pentopyranoside derivatives were treated with Me3Al in order to investigate the influence of structural parameters on the methyl group transfer in the endocyclic alkylative cleavage reaction of these substrates. A cyclic CH ··· O hydrogen bonded model is suggested as an intermediate, which is used to explain the stereoselectivities for different substrates. In several, cases the diastereoselectivities were better than 9:1.
