151662-55-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 151662-55-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,6,6 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 151662-55:
(8*1)+(7*5)+(6*1)+(5*6)+(4*6)+(3*2)+(2*5)+(1*5)=124
124 % 10 = 4
So 151662-55-4 is a valid CAS Registry Number.

Synthesis of pyranoid and furanoid glycals from glycosyl sulfoxides by treatment with organolithium reagents

Gomez, Ana M.,Casillas, Marta,Barrio, Aitor,Gawel, Anna,Lopez, J. Cristobal

experimental part, p. 3933 - 3942 (2009/04/08)

Glycosyl sulfoxides can be conveniently transformed into pyranoid or furanoid glycals by treatment with organolithium reagents. The more likely reaction pathway involves a sulfoxide/metal exchange reaction to generate a glycosyllithium derivative that und

Alkyloxytris(dimethylamino)phosphonium Salts. Part 21. Anomeric Hydroxy-group Activation of 2,3:4,6-Di-O-isopropylidene-α-D-mannopyranose, Thioglycosylation and Glycosylation

Chretien, Francoise,Chapleur, Yves,Castro, Bertrand,Gross, Bernard

, p. 381 - 384 (2007/10/02)

The action of carbon tetrachloride and tris(dimethylamino)phosphine at low temperature on 2,3:4,6-di-O-isopropylidene-α-D-mannopyranose affords the α anomeric form of the corresponding alkoxytris(dimethylamino)phosphonium chloride.The condensation of arom
