The chemical compound "O2,O3,O6-trimethyl-O4-(toluene-4-sulfonyl)-D-glucose" is a complex organic molecule derived from D-glucose, a monosaccharide. It features three methyl groups attached to the second, third, and sixth oxygen atoms of the glucose molecule, and a toluene-4-sulfonyl group attached to the fourth oxygen atom. This modification of D-glucose introduces unique chemical properties and reactivity, which can be significant in various chemical and biological applications, such as in the synthesis of complex carbohydrates or as a protecting group in organic synthesis. The toluene-4-sulfonyl group, in particular, is known for its stability and can be used to protect hydroxyl groups during chemical reactions, making O2,O3,O6-trimethyl-O4-(toluene-4-sulfonyl)-D-glucose potentially useful in the preparation of more complex organic molecules where selective protection and deprotection of functional groups are required.
The CAS Registry Mumber 6997-05-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,9 and 7 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 6997-05: (6*6)+(5*9)+(4*9)+(3*7)+(2*0)+(1*5)=143 143 % 10 = 3 So 6997-05-3 is a valid CAS Registry Number.
