Check Digit Verification of cas no

The CAS Registry Mumber 1000780-45-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,0,7,8 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1000780-45:
(9*1)+(8*0)+(7*0)+(6*0)+(5*7)+(4*8)+(3*0)+(2*4)+(1*5)=89
89 % 10 = 9
So 1000780-45-9 is a valid CAS Registry Number.

Stereoselective synthesis of the 3-aminopropyl glycosides of α-D-xyl-(1→3)-β-D-glc and α-D-xyl-(1→3)-α-D- xyl-(1→3)-β-D-glc and of their corresponding N-octanoyl derivatives

The stereoselective synthesis of the spacer-armed disaccharide α-D-Xyl-(1→3)-β-D-Glc-O-(CH2)3NH 2 and trisaccharide α-D-Xyl-(1→3)-α-D-Xyl-(1→3) -β-D-Glc-O-(CH2)3NH2, as well as of their N-octanoyl derivatives, was performed for their subsequent use as acceptors and reference samples in xylosyltransferase assays. These structures are found as O-linked glycans on epidermal growth factor (EGF) domains of several blood-clotting factors and Notch. The target products were prepared by glycosylation with a 3-O-acetylated xylosyl donor that was previously found to be an effective α-xylosylating agent. However, in this paper we show that the structure of the glycosyl acceptor could influence the stereochemical results of the glycosylation and even lead to reversed stereoselectivity in the case of one acceptor.
