Calculate Digit Verification of CAS Registry Number 181047-31:
(8*1)+(7*8)+(6*1)+(5*0)+(4*4)+(3*7)+(2*3)+(1*1)=114
114 % 10 = 4
So 181047-31-4 is a valid CAS Registry Number.

Inactivation of serine protease, α-chymotrypsin by fluorinated phenylalanine analogues

Ohba, Tsuyoshi,Ikeda, Eitatsu,Takei, Hisashi

, p. 1875 - 1880 (1996)

Fluorinated phenylalanine analogues were found to be slow-binding or reversible competitive inhibitors of α-chymotrypsin. A series of these compounds were designed to inactivate α-chymotrypsin as a result of the formation of hydrogen-bonding between fluorine atom of the inhibitors and the amide protons known as oxy-anion hole in the active-site of serine and cysteine proteases.
