106988-66-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 106988-66-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,9,8 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 106988-66:
(8*1)+(7*0)+(6*6)+(5*9)+(4*8)+(3*8)+(2*6)+(1*6)=163
163 % 10 = 3
So 106988-66-3 is a valid CAS Registry Number.

Improvement in O -> C Glycoside Rearrangement Approach to C-Aryl Glycosides: Use of 1-O-Acetyl Sugar as Stable but Efficient Glycosyl Donor

Matsumoto, Takashi,Hosoya, Takamitsu,Suzuki, Keisuke

, p. 4629 - 4632 (2007/10/02)

1-O-Acetyl sugars serve as efficient glycosyl donor in the O -> C-glycoside rearrangement approach to C-aryl glycosides.Model study was carried out on three types of 2-deoxy-glycosyl acetates including amino sugar derivative.Comparison of the promoters, Cp2HfCl2-AgClO4, SnCl4, BF3*OEt2 is described.

Synthetic Study toward Vineomycins. Synthesis of C-Aryl Glycoside Sector via Cp2HfCl2-AgClO4-Promoted Tactics

Matsumoto, Takashi,Katsuki, Miyoko,Jona, Hideki,Suzuki, Keisuke

, p. 6185 - 6188 (2007/10/02)

Regio- and stereo-controlled formation of C-aryl β-D-olivoside linkage is achieved by the reaction of naphthol or anthrol derivatives with D-olivosyl fluoride.The reaction is efficiently promoted by Cp2HfCl2-AgClO4 and the bond formation occurs selectivit

Syntheses of Selectively Alkylated Enol Ethers in the L-ribo Series

Koepper, Sabine,Lundt, Inge,Pedersen, Christian,Thiem, Joachim

, p. 531 - 536 (2007/10/02)

The reduction of enulose 1a predominantly leads to L-digitoxal (3a), although this method presents a sluggish reaction with moderate yields.In contrast, the preparation from L-digitoxose (4a) in a three-step one-pot procedure represents an advantageous approach.Regioselective 3- or 4-O-alkylations are achieved by phase-transfer catalysis method or via stannylidene intermediates to give monosaccharide precursors of the L-ribo series valuable for further interglycosidic linking.
