Purification Methods
D-Galactose (40g) is dissolved in hot H2O to establish the equilibrium of and anomers; then the solution is cooled to 0o and poured into absolute EtOH (500mL). Stir vigorously and crystallisation occurs within a few minutes, and more rapidly if seeded, filter the crystals immediately (7g, [] D 20 +65o (initial, c 4 in H2O). This mixture of and anomers is further separated by dissolving in an equal weight of cold H2O, filtering and adding to ice cold absolute EtOH (250mL) and stirring for 1minute when crystals separate, then filter them off. After two such crystallisations, the initial [] D 20 is +53o. This can be further purified by shaking with 80% EtOH for 2minutes, filtering, washing with EtOH and Et2O, and drying in a vacuum desiccator to give -Dgalactose (15g) with m 167o, [ ] D 20 +52o (initial, c 4 in H2O) mutarotating to +80.4o. Acetylation of Dgalactose with hot NaOAc/Ac2O gives -D-galactopyranoside pentaacetate m 1 4 2o, [ ] D 25 +25 (c 4 in CHCl3).

Check Digit Verification of cas no
The CAS Registry Mumber 7296-64-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,9 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7296-64:
(6*7)+(5*2)+(4*9)+(3*6)+(2*6)+(1*4)=122
122 % 10 = 2
So 7296-64-2 is a valid CAS Registry Number.

Immobilization of β-galactosidase onto Sepharose and stabilization in room temperature ionic liquids
Singh, Natasha R.,Narinesingh, Dyer,Singh, Gurdial
, p. 19 - 27 (2010)
The hydrolysis of o-nitrophenyl-β-d-galactopyranoside (ONPG) by β-galactosidase immobilized on Sepharose CL-4B was investigated in five different ionic liquids (ILs), 1-butyl-3-methylimidazolium X-; [X = CF3SO3-, BF4-, PF6-, CH3SO4-and N(CN)2-]. Michaelis-Menten kinetic studies were conducted in phosphate buffer and in the five ionic liquids. For the immobilized enzyme in the ILs, the Km values were lower (0.36-1.2 mmol ONPG) while the Vmax values were higher (0.04-0.008 min- 1) compared to those in aqueous phosphate buffer suggesting a marked increase in the efficiency of the immobilized enzyme in the ionic liquid. For the free enzyme in the ionic liquids, the Km values, in general, were larger (0.45-4.96 mmol ONPG) than those of the immobilized enzyme in the ionic liquid. A postulated mechanism for the hydrolysis is suggested, involving interception of the intermediate oxonium ion species by the counter ion of the ionic liquid, thereby enabling the hydrolysis to occur at a faster rate.
