183854-98-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 183854-98-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,8,5 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 183854-98:
(8*1)+(7*8)+(6*3)+(5*8)+(4*5)+(3*4)+(2*9)+(1*8)=180
180 % 10 = 0
So 183854-98-0 is a valid CAS Registry Number.

Nonsymmetrically substituted cyclic urea HIV protease inhibitors
Wilkerson, Wendell W.,Dax, Scott,Cheatham, Walter W.
, p. 4079 - 4088 (2007/10/03)
A series of nonsymmetrically substituted cyclic ureacarboxamides was synthesized and evaluated for antiviral activity as a function of the inhibition of HIV-protease. Selected protease inhibitors were also evaluated for oral bioavailability. The synthesis
