"O1,O3,O4,O5-Tetramethyl-D-fructose" is a derivative of D-fructose, a naturally occurring sugar found in fruits and honey. In O1,O3,O4,O5-Tetramethyl-D-fructose, four hydroxyl groups (-OH) of the D-fructose molecule are replaced by four methyl groups (-CH3), specifically at the 1st, 3rd, 4th, and 5th carbon atoms. This modification alters the chemical properties of the original sugar, potentially affecting its solubility, reactivity, and biological activity. The resulting compound is a synthetic, highly substituted sugar that may have applications in chemical research, pharmaceuticals, or as a sweetener in food products.
The CAS Registry Mumber 4451-15-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,5 and 1 respectively; the second part has 2 digits, 1 and 5 respectively. Calculate Digit Verification of CAS Registry Number 4451-15: (6*4)+(5*4)+(4*5)+(3*1)+(2*1)+(1*5)=74 74 % 10 = 4 So 4451-15-4 is a valid CAS Registry Number.
