Check Digit Verification of cas no

The CAS Registry Mumber 173465-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,4,6 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 173465-71:
(8*1)+(7*7)+(6*3)+(5*4)+(4*6)+(3*5)+(2*7)+(1*1)=149
149 % 10 = 9
So 173465-71-9 is a valid CAS Registry Number.

Synthetic route for 14C-labeling of a bioactive lipid A analogue

Fukase,Aoki,Kinoshita,Suda,Kurosawa,Zahringer,Rietschel,Kusumoto

, p. 8645 - 8648 (2007/10/02)

A synthetic route for 14C-labeling of a phosphonooxyethyl (PE) analogue of E. coli lipid A was established by cold experiments. The PE analogue is chemically more stable than natural lipid A but shows particularly identical biological activity. The glycosidation of ethylene glycol unit as the 14C-labeled position was effected with a disaccharide thioglycoside by use of a hypervalent iodine reagent, PhIO-SnClO4-AgClO4, as an activator. p-Methoxybenzyl group used for the protection of the distal hydroxyl group of ethylene glycol was selectively removed by trimethylsilyl triflate in CH3CN-CH2Cl2 followed by phosphorylation and deprotection gave the target compound.
