Check Digit Verification of cas no

The CAS Registry Mumber 262293-16-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,2,2,9 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 262293-16:
(8*2)+(7*6)+(6*2)+(5*2)+(4*9)+(3*3)+(2*1)+(1*6)=133
133 % 10 = 3
So 262293-16-3 is a valid CAS Registry Number.

Synthesis and in vitro evaluation of inhibitors of intestinal cholesterol absorption

Kv?rn?, Lisbet,Werder, Moritz,Hauser, Helmut,Carreira, Erick M.

, p. 6035 - 6053 (2007/10/03)

We have utilized our recently developed in vitro assay to address two key questions in the design of small-molecule cholesterol absorption inhibitors using ezetimibe, the only drug yet approved for the inhibition of cholesterol absorption in the small int

The synthesis of an O,C-trisaccharide: The O,C-analog of methyl 4'-O-β- D-glucopyranosylgentiobioside

Spak, Stephen J.,Martin, Olivier R.

, p. 217 - 224 (2007/10/03)

The synthesis of an O,C-trisaccharide, namely methyl O-β-D- glucopyranosyl-(1→4)-C-β-D-glucopyranosyl-(1→6)-α-D-glucopyranoside, was achieved in 14 steps by way of the nitro-aldol coupling of hepta-O-acetyl-β- cellobiosylnitromethane and methyl 6-aldehydo-2,3,4-tri-O-benzyl-α-D-gluco- hexodialdo-1,5-pyranoside, followed by the elaboration of the coupling product. The resulting O,C-trisaccharide constitutes a potential inhibitor of the β-glucanases of the cellulase family. The perbenzylated derivative of cellobiosylnitromethane was also prepared. Both disaccharide-C-glycosides constitute useful starting materials for the preparation of higher mixed O,C- oligosaccharides.
