290308-58-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 290308-58-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,0,3,0 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 290308-58:
(8*2)+(7*9)+(6*0)+(5*3)+(4*0)+(3*8)+(2*5)+(1*8)=136
136 % 10 = 6
So 290308-58-6 is a valid CAS Registry Number.

Facile solid phase synthesis of YEE(ah-GalNAc)3, a ligand with known high affinity for the asialoglycoprotein receptor

Jiaang, Weir-Torn,Tseng, Ping-Hui,Chen, Shui-Tein

, p. 797 - 800 (2007/10/03)

A simple cluster glycoside, containing three residues of N- acetylgalactosamine with proper inter-residual distances, can be a high- affinity ligand for the asialoglycoprotein receptor (ASGPr) of mammalian liver. Tris(GalNAc-aminohexyl)glycoside of tyrosyl(glutamyl)glutamate YEE(ah- GalNAc)3 1, which is known to have sub-nanomolar affinity for the asialoglycoprotein receptor, was efficiently synthesized by using succinic acid as a linker to anchor GalNAc-aminohexyl glycoside to solid phase resin, followed by coupling the building blocks of Fmoc-(ah-α-GalNAcAc3)Glu and Fmoc-Tyr-OH to obtain YEE(ah-GalNAc)3 with a total yield of 83%.
