Check Digit Verification of cas no

The CAS Registry Mumber 57198-52-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,1,9 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57198-52:
(7*5)+(6*7)+(5*1)+(4*9)+(3*8)+(2*5)+(1*2)=154
154 % 10 = 4
So 57198-52-4 is a valid CAS Registry Number.

Inhibition of serine proteases: Activity of 1,3-diazetidine-2,4-diones

Aoyama, Yasunori,Uenaka, Masaaki,Konoike, Toshiro,Hayasaki-Kajiwara, Yoko,Naya, Noriyuki,Nakajima, Masatoshi

, p. 1691 - 1694 (2007/10/03)

The present work demonstrates that the 1,3-diazetidine-2,4-dione nucleus is effective as a scaffold of serine protease inhibitors. Compound 1 displayed high activity against human cathepsin G and α-chymotrypsin (0.39, 0.69 nM). Compound 6 exhibited 0.85 nM inhibition of human chymase. Compound 10 was a selective inhibitor against human neutrophil elastase.
