151731-16-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 151731-16-7 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 6 respectively.
Calculate Digit Verification of CAS Registry Number 151731-16:
(8*1)+(7*5)+(6*1)+(5*7)+(4*3)+(3*1)+(2*1)+(1*6)=107
107 % 10 = 7
So 151731-16-7 is a valid CAS Registry Number.

A convenient synthesis of glycosylated hydantoins as potential antiviral agents
Khodair, Ahmed I.
, p. 9 - 26 (2007/10/03)
Reaction of 5-arylidene-2-thiohydantoins 3a-d with glycosyl halides 4a,b under alkaline conditions gave the respective bisglycosylated derivatives 5a-h. Deacetylation with ammonia in methanol caused a change of the S-glycosyl residue and gave the N-3 glyc
