Methyl 2,3-di-O-benzyl-6-O-toluene-p-sulfonyl-β-D-galactopyranoside is a complex organic compound with the molecular formula C27H30O7S. It is a derivative of β-D-galactopyranoside, a monosaccharide sugar, where the hydroxyl groups at the 2nd and 3rd carbon atoms are protected by benzyl groups, and the hydroxyl group at the 6th carbon is protected by a toluene-p-sulfonyl group. methyl 2,3-di-O-benzyl-6-O-toluene-p-sulfonyl-β-D-galactopyranoside is commonly used in organic synthesis, particularly in the preparation of complex carbohydrates and glycoconjugates, due to its ability to protect specific functional groups during chemical reactions. The benzyl and toluene-p-sulfonyl protecting groups can be selectively removed under certain conditions, allowing for the controlled synthesis of more complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 6988-41-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,8 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6988-41:
(6*6)+(5*9)+(4*8)+(3*8)+(2*4)+(1*1)=146
146 % 10 = 6
So 6988-41-6 is a valid CAS Registry Number.
