O3-methyl-L-arabinose, also known as 3-O-methyl-L-arabinose, is a monosaccharide derivative of L-arabinose, a naturally occurring pentose sugar. It is characterized by the presence of a methyl group (-CH3) attached to the third carbon atom of the L-arabinose molecule. This modification can influence the chemical properties and reactivity of the sugar, potentially affecting its interactions with enzymes, other sugars, or in biological systems. O3-methyl-L-arabinose is of interest in various fields, including biochemistry, pharmaceuticals, and materials science, where it may be used as a building block for the synthesis of complex carbohydrates or as a probe to study sugar metabolism and recognition.
The CAS Registry Mumber 6866-63-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,6 and 6 respectively; the second part has 2 digits, 6 and 3 respectively. Calculate Digit Verification of CAS Registry Number 6866-63: (6*6)+(5*8)+(4*6)+(3*6)+(2*6)+(1*3)=133 133 % 10 = 3 So 6866-63-3 is a valid CAS Registry Number.
