6-deoxy-D-erythro-[2,5]hexodiulose is a monosaccharide, a type of sugar molecule, that is structurally similar to common sugars but with a key difference: it lacks an oxygen atom at the sixth carbon position, hence the term "6-deoxy." This unique feature distinguishes it from other sugars and can affect its chemical properties and reactivity. The "D-erythro" configuration refers to the specific arrangement of atoms in the molecule, which is important for understanding its stereochemistry. The "[2,5]hexodiulose" part of the name indicates that it is a hexose sugar with two aldehyde groups, one at the second carbon and one at the fifth carbon, which are key functional groups in sugar chemistry. 6-deoxy-D-erythro-[2,5]hexodiulose is of interest in the field of organic chemistry and biochemistry, particularly in studies related to sugar metabolism and the synthesis of complex carbohydrates.
The CAS Registry Mumber 7699-34-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,9 and 9 respectively; the second part has 2 digits, 3 and 4 respectively. Calculate Digit Verification of CAS Registry Number 7699-34: (6*7)+(5*6)+(4*9)+(3*9)+(2*3)+(1*4)=145 145 % 10 = 5 So 7699-34-5 is a valid CAS Registry Number.
