Check Digit Verification of cas no

The CAS Registry Mumber 1426550-76-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,6,5,5 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1426550-76:
(9*1)+(8*4)+(7*2)+(6*6)+(5*5)+(4*5)+(3*0)+(2*7)+(1*6)=156
156 % 10 = 6
So 1426550-76-6 is a valid CAS Registry Number.

The development of an aza-C-glycoside library based on a tandem staudinger/aza-wittig/ugi three-component reaction

Wennekes, Tom,Bonger, Kimberly M.,Vogel, Katrin,Van Den Berg, Richard J. B. H. N.,Van Der Marel, Gijsbert A.,Overkleeft, Herman S.,Strijland, Anneke,Donker-Koopman, Wilma E.,Aerts, Johannes M. F. G.

We report the tandem Staudinger/aza-Wittig/Ugi three-component reaction mediated synthesis of a 64-member compound library of aza-C-glycosides. The library is composed of four pyrrolidine and three piperidine scaffolds, onto which a number of functional groups is grafted to form seven sublibraries. Variation in the library is achieved by transformation of two pentoses and a hexose into the corresponding 4-azidopentanal and 5-azidohexanal derivatives as precursors for the Staudinger/aza-Wittig process. Further variation is achieved by using different isocyanides as well as protective- and functional-group manipulations on the fully protected Ugi-3CR intermediates. Preliminary biological evaluation of the compound library revealed several low micromolar inhibitors of human acid glucosylceramidase.
