151731-18-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 151731-18-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,7,3 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 151731-18:
(8*1)+(7*5)+(6*1)+(5*7)+(4*3)+(3*1)+(2*1)+(1*8)=109
109 % 10 = 9
So 151731-18-9 is a valid CAS Registry Number.

S-Glucosylated hydantoins as new antiviral agents
El-Barbary,Khodair,Pedersen,Nielsen
, p. 73 - 77 (1994)
S-Glycosylation took place on reaction of 5-alkylidene- and 5-arylidene- 3-aryl-2-thiohydantoins with glycosyl halides under alkaline conditions. Bisglucosylation also took place when N-3 unsubstituted hydantoins were reacted. The bisglucosylated hydantoi
