Methyl-[O2,O3,O6-trimethyl-O4-(toluene-4-sulfonyl)-β-D-glucopyranoside] is a complex organic compound that consists of a β-D-glucopyranoside sugar moiety with various modifications. The molecule features three methyl groups attached to the second, third, and sixth oxygen atoms (O2, O3, and O6), and a toluene-4-sulfonyl group attached to the fourth oxygen atom (O4). This chemical structure is significant in the field of carbohydrate chemistry, as it represents a derivative of a common sugar with specific functional groups that can be used in various chemical reactions and 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 a common protecting group used to shield certain functional groups during chemical reactions, allowing for selective modification of other parts of the molecule.
The CAS Registry Mumber 3149-36-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,4 and 9 respectively; the second part has 2 digits, 3 and 6 respectively. Calculate Digit Verification of CAS Registry Number 3149-36: (6*3)+(5*1)+(4*4)+(3*9)+(2*3)+(1*6)=78 78 % 10 = 8 So 3149-36-8 is a valid CAS Registry Number.
