General Description
The chemical with the non-preferred name "(2S,3R,4R,5R)-4-{[(2R,3R,4S,5R,6S)-3,4,5,6-tetrahydroxytetrahydro-2H-pyran-2-yl]oxy}hexane-1,2,3,5,6-pentol dihydrate" is a compound with a complex molecular structure. It contains multiple hydroxyl (OH) groups and is in the form of a dihydrate. The compound is composed of a hexane backbone linked to a tetrahydroxytetrahydro-2H-pyran-2-yl group through an oxy linkage. It is a highly hydrophilic and water-soluble molecule. The specific stereochemistry of the compound is indicated by the letters S and R, which denote the spatial orientation of the substituent groups around the chiral centers of the molecule.
Check Digit Verification of cas no
The CAS Registry Mumber 81025-03-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,2 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81025-03:
(7*8)+(6*1)+(5*0)+(4*2)+(3*5)+(2*0)+(1*3)=88
88 % 10 = 8
So 81025-03-8 is a valid CAS Registry Number.

Method of preparing lacitol monohydrate and dihydrate
-
, (2008/06/13)
The invention relates to the new product lactitol monohydrate and to a method for the production of crystalline lactitol. The crystalline lactitol monohydrate can be obtained bij seeding an aqueous lactitol solution of a special concentration under special conditions causing the lactitol monohydrate to crystallize and recovering the product. From the mother liquor a further amount of lactitol dihydrate can be recovered. Crystalline lactitol dihydrate can be obtained using different special conditions. Lactitolmonohydrate can further be obtained by mixing one part bij weight of an aqueous lactitol solution of a suited concentration with 1 tot 3 parts bij weight of methanol or ethanol and cooling the mixture to 15° tot 25° C.
