"O4,O6-((Ξ)-ethylidene)-D-galactose" is a complex carbohydrate derivative, specifically a modified form of D-galactose, a monosaccharide that is a component of lactose and other disaccharides. The chemical name indicates that it has undergone a chemical modification where an ethylidene group (Ξ) has been introduced between the 4th and 6th hydroxyl groups (OH) of the D-galactose molecule. This modification can alter the reactivity and properties of the sugar, potentially affecting its solubility, stability, or ability to interact with other molecules. Such chemical modifications are often used in the synthesis of pharmaceuticals, food additives, or for research purposes to study the effects of structural changes on biological activity.
The CAS Registry Mumber 6207-17-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,0 and 7 respectively; the second part has 2 digits, 1 and 7 respectively. Calculate Digit Verification of CAS Registry Number 6207-17: (6*6)+(5*2)+(4*0)+(3*7)+(2*1)+(1*7)=76 76 % 10 = 6 So 6207-17-6 is a valid CAS Registry Number.
