Penta-O-acetyl-aldehydo-D-galactose (Ξ)-O-ethyl S-methyl monothioacetal is a complex organic compound derived from D-galactose, a monosaccharide sugar. This chemical is characterized by the presence of five acetyl groups attached to the hydroxyl groups of the galactose molecule, which protect the sugar's hydroxyl groups during chemical reactions. The aldehydo group indicates the presence of a carbonyl group at the reducing end of the sugar, while the Ξ notation suggests a specific configuration or isomer of the molecule. The O-ethyl S-methyl monothioacetal part of the name indicates that an ethyl group is attached to the oxygen of the sugar, and a methyl group is attached to the sulfur of a thioacetal group, which is a type of protecting group used in organic synthesis to prevent unwanted reactions at the carbonyl group. penta-O-acetyl-aldehydo-D-galactose (Ξ)-O-ethyl S-methyl monothioacetal is significant in the field of carbohydrate chemistry and may be used in the synthesis of various biologically active molecules or as an intermediate in the preparation of complex organic compounds.

5120-89-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5120-89-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,2 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.Calculate Digit Verification of CAS Registry Number 5120-89:
(6*5)+(5*1)+(4*2)+(3*0)+(2*8)+(1*9)=68
68 % 10 = 8
So 5120-89-8 is a valid CAS Registry Number.
