2,5-Anhydro-D-mannaric acid, also known as 2,5-anhydro-D-mannose, is a naturally occurring organic compound that belongs to the class of sugars, specifically a type of sugar alcohol known as a polyol. It is a derivative of D-mannose, a monosaccharide, where the hydroxyl groups at the 2nd and 5th carbon atoms are removed, resulting in the formation of an anhydro ring. 2,5-anhydro-D-mannaric acid is of interest in the field of carbohydrate chemistry and has potential applications in the synthesis of various biologically active compounds and pharmaceuticals. It is typically synthesized through chemical or enzymatic methods and can be used as a building block for the creation of more complex molecules.
The CAS Registry Mumber 643-47-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 3 respectively; the second part has 2 digits, 4 and 7 respectively. Calculate Digit Verification of CAS Registry Number 643-47: (5*6)+(4*4)+(3*3)+(2*4)+(1*7)=70 70 % 10 = 0 So 643-47-0 is a valid CAS Registry Number.
