199589-52-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 199589-52-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,5,8 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 199589-52:
(8*1)+(7*9)+(6*9)+(5*5)+(4*8)+(3*9)+(2*5)+(1*2)=221
221 % 10 = 1
So 199589-52-1 is a valid CAS Registry Number.

The design and synthesis of a novel series of indole derived selective ETA antagonists
Rawson, David J.,Dack, Kevin N.,Dickinson, Roger P.,James, Kim
, p. 125 - 128 (2007/10/03)
Conformational constraint has been used as the key design element in the identification of a series of potent and selective ETA antagonists. The most potent antagonist, 32, (ETA IC50 = 0.55 nM) is 722-fold selective over t
