Check Digit Verification of cas no

The CAS Registry Mumber 21291-36-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,9 and 1 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21291-36:
(7*2)+(6*1)+(5*2)+(4*9)+(3*1)+(2*3)+(1*6)=81
81 % 10 = 1
So 21291-36-1 is a valid CAS Registry Number.

Gluco-oligomers initially formed by the reuteransucrase enzyme of Lactobacillus reuteri 121 incubated with sucrose and malto-oligosaccharides

Dobruchowska, Justyna M,Meng, Xiangfeng,Leemhuis, Hans,Gerwig, Gerrit J,Dijkhuizen, Lubbert,Kamerling, Johannis P.

, p. 1084 - 1096 (2013/08/23)

The probiotic bacterium Lactobacillus reuteri 121 produces a complex, branched (1 → 4, 1 → 6)-α-D-glucan as extracellular polysaccharide (reuteran) from sucrose (Suc), using a single glucansucrase/glucosyltransferase (GTFA) enzyme (reuteransucrase). To gain insight into the reaction/product specificity of the GTFA enzyme and the mechanism of reuteran formation, incubations with Suc and/or a series of malto-oligosaccharides (MOSs) (degree of polymerization (DP2-DP6)) were followed in time. The structures of the initially formed products, isolated via high-performance anion-exchange chromatography, were analyzed by matrix-assisted laser-desorption ionization time-of-flight mass spectrometry and 1D/2D 1H/13C NMR spectroscopy. Incubations with Suc only, acting as both donor and acceptor, resulted in elongation of Suc with glucose (Glc) units via alternating (α1 → 4) and (α1 → 6) linkages, yielding linear gluco-oligosaccharides up to at least DP ~ 12. Simultaneously with the ensemble of oligosaccharides, polymeric material was formed early on, suggesting that alternan fragments longer than DP ~ 12 have higher affinity with the GTFA enzyme and are quickly extended, yielding high-molecular-mass branched reuteran (4 × 107 Da). MOSs (DP2-DP6) in the absence of Suc turned out to be poor substrates. Incubations of GTFA with Suc plus MOSs as substrates resulted in preferential elongation of MOSs (acceptors) with Glc units from Suc (donor). This apparently reflects the higher affinity of GTFA for MOSs compared with Suc. In accordance with the GTFA specificity, most prominent products were oligosaccharides with an (α1 → 4)/(α1 → 6) alternating structure. The Author 2013. Published by Oxford University Press.

Synthesis of a novel prebiotic trisaccharide by a type i α-glucosidase from B. licheniformis strain TH4-2

Nimpiboon, Pitchanan,Nakapong, Santhana,Pichyangkura, Rath,Ito, Kazuo,Pongsawasdi, Piamsook

experimental part, p. 448 - 457 (2012/01/06)

The use of α-glucosidase from Bacillus licheniformis TH4-2 in the glucosyl transfer reaction for the synthesis of oligosaccharides (OS) was evaluated. The conditions for α-glucosidase production were optimized. The enzyme was 112-fold purified with a 28% yield. The molecular mass was 64 kDa, and the optimum pH and temperature were 6.0 and 45 °C. The highest hydrolytic activity was observed towards p-nitrophenyl α-d-glucopyranoside followed by isomaltose, sucrose and maltose, supporting that it is a type I α-glucosidase. The enzyme could synthesize OS by transglucosylation from sucrose donor using various saccharides as acceptor. Melibiose, an α-galactoside, was selected as an efficient and interesting acceptor. TLC and HPLC analysis of the products revealed that the optimum condition for OS production was pH 6.0 with 15% melibiose, 5% sucrose and 5 U/ml enzyme at 45 °C for 24 h. Under these conditions two product peaks were observed in the HPLC profile with yields of 17.2% and 3.3%. The main product was isolated by Sephadex LH-20 column and analyzed by MS and NMR as the novel 504 Daltons trisaccharide, α-d-glucopyranosyl-(1 → 6)-α-d-galactopyranosyl- (1 → 6)-d-glucopyranose. The prebiotic nature of this product was suggested from its resistance to hydrolysis by rat intestinal acetone powder containing digestible enzymes of rat intestine.

First direct glycosylation of unprotected nonreducing mono- and disaccharides

Steinmann, Andreas,Thimm, Julian,Thiem, Joachim

, p. 5506 - 5513 (2008/09/17)

The first single-step random-glycosylation methodology for fully unprotected glycosyl acceptors is reported by random glycosylation leading to all possible regioisomers. For such systems conventional glycosylation methods such as Koenigs-Knorr glycosylation, Schmidt's trichloroacetimidate glycosylation and reactions employing glycosyl fluoride donors fail entirely. Starting from unprotected nonreducing saccharides, the glycosylation of β-glucosylated and β-galactosylated monosaccharides (Glc, Gal), symmetric disaccharides (e.g. α,α-trehaloses) as well as unsymmetric disaccharides (e.g. sucrose) were studied. The influence of base type and concentration were examined. Several libraries of di- and trisaccharides were generated. All regioisomers were formed in approximately equal proportions, and their partial separation was achieved by flash column chromatography. Even though it appears that overall yields are lower when comparing to classical protecting-group chemistry, this synthetic effort may be superior especially for access to higher saccharides.

REGIOSELECTIVE SYNTHESIS OF TRISACCHARIDES BY USE OF A REVERSED HYDROLYSIS ACTIVITY OF α- AND β-D-GALACTOSIDASE

Ajisaka, Katsumi,Fujimoto, Hiroshi

, p. 139 - 146 (2007/10/02)

Incubation of a solution containing D-galactose and a high concentration of sucrose in the presence of α-D-galactosidase from M. vinacea afforded raffinose and planteose in a ratio of ca. 3:2.On the other hand, circulation of a solution of D-galactose and sucrose through a reaction system consisting of columns, in series, of immobilized α-D-galactosidase and activated carbon gave only raffinose, eluted from the activated carbon column in a 17.6percent yield.Similarly, only isoraffinose was obtained in 10.6percent yield by the continuous method using an immobilized column of β-D-galactosidase from E. coli.
