Check Digit Verification of cas no

The CAS Registry Mumber 566200-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,6,6,2,0 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 566200-19:
(8*5)+(7*6)+(6*6)+(5*2)+(4*0)+(3*0)+(2*1)+(1*9)=139
139 % 10 = 9
So 566200-19-9 is a valid CAS Registry Number.

A novel method for the formation of N-glycosides using hydroxamate

Nakano, Jun,Ichiyanagi, Tsuyoshi,Ohta, Hiromichi,Ito, Yukishige

, p. 2853 - 2856 (2003)

Direct formation of Asn-linked carbohydrate by N-glycosylation has been difficult, because of the lack of nucleophilicity of carboxamide nitrogen. We report here the novel N-glycosylation using Asn hydroxamate as a glycosyl acceptor. Reaction with glycosyl fluoride or glycosyl trichloroacetimidate afforded N-glycoside and subsequent reduction with SmI2 gave Asn-linked glucose. Carbamate derived hydroxamates proved to have even enhanced reactivity to give N-glycosides in high yields.
