118499-49-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 118499-49-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,4,9 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 118499-49:
(8*1)+(7*1)+(6*8)+(5*4)+(4*9)+(3*9)+(2*4)+(1*9)=163
163 % 10 = 3
So 118499-49-3 is a valid CAS Registry Number.

SYNTHESIS OF 1,5-LACTONES OF 3-DEOXY-D-manno-2-OCTULOPYRANOSONIC ACID ( KDO)

Auzanneau, France-Isabelle,Charon, Daniel,Szabo, Ladislas,Merienne, Claude

, p. 125 - 136 (2007/10/02)

An unambigous synthesis of methyl 3-deoxy-α-D-manno-2-octulopyranosidono-1,5-lactone from methyl (methyl 3-deoxy-α-D-manno-octulopyranosid)onate via the 7,8-O-isopropylidene derivative is described.Treatment of the 4,5-stannylene derivative of this acetal with benzyl bromide gave the 1,5-lactone from which the protecting groups were removed.The acetylated 1,5-lactone was produced by acetylation of ammonium 3-deoxy-D-manno-2-octulosonate or treatment of the pyridinium salt with dicyclohexylcarbodi-imide and acetylation.No lactone was produced when only HO-7 was unsubstituted.When treated with an excess of 2-methoxypropene, methyl (methyl 3-deoxy-α-D-manno-2-octulopyranosid)onate afforded the 4,5:7,8-di-O-isopropylidene derivative, from which the 7,8-acetal group could be removed selectively.
