89499-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89499-98-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,4,9 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 89499-98:
(7*8)+(6*9)+(5*4)+(4*9)+(3*9)+(2*9)+(1*8)=219
219 % 10 = 9
So 89499-98-9 is a valid CAS Registry Number.

2,3,1',3'4',6'-Hexa-O-benzylsucrose was obtained by mild acid-catalysed hydrolysis of the 4,6-O-isopropylidene derivative and then converted into its 4,6-di-O-mesyl derivative. Selective displacement of this disulphonate with fluoride anion (from tetrabut
