118724-88-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118724-88-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,7,2 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 118724-88:
(8*1)+(7*1)+(6*8)+(5*7)+(4*2)+(3*4)+(2*8)+(1*8)=142
142 % 10 = 2
So 118724-88-2 is a valid CAS Registry Number.

A series of disubstituted catechol derivatives was synthesized and tested as potential COMT inhibitors.The most active compounds were more than 1000 times more potent (IC 50 = 3-6 nM) in vitro than the known COMT inhibitor, 3',4'-dihydroxy-2-methylpropiop
