6-Chloro-tri-O-chlorosulfonyl-α-D-6-deoxy-mannopyranosyl chloride is a complex organic compound with the molecular formula C7H8Cl7O7S3. It is a derivative of a sugar molecule, specifically a 6-deoxy-mannopyranose, which has been modified with a chloro group at the 6-position and three chlorosulfonyl groups attached to the hydroxyl groups at the 2, 3, and 4 positions. 6-chloro-tri-O-chlorosulfonyl-α-D-6-deoxy-mannopyranosyl chloride is of interest in the field of carbohydrate chemistry and may have potential applications in the synthesis of complex glycoconjugates or as a building block for the development of new pharmaceuticals. The presence of multiple chloro and chlorosulfonyl groups makes it a highly reactive intermediate, which can be further functionalized or used in the formation of glycosidic linkages.

Check Digit Verification of cas no

The CAS Registry Mumber 4990-87-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,9 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4990-87:
(6*4)+(5*9)+(4*9)+(3*0)+(2*8)+(1*7)=128
128 % 10 = 8
So 4990-87-8 is a valid CAS Registry Number.
