Check Digit Verification of cas no

The CAS Registry Mumber 109803-76-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,0 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 109803-76:
(8*1)+(7*0)+(6*9)+(5*8)+(4*0)+(3*3)+(2*7)+(1*6)=131
131 % 10 = 1
So 109803-76-1 is a valid CAS Registry Number.

Tetsuhashi, Masashi,Ishikawa, Minoru,Hashimoto, Mariko,Hashimoto, Yuichi,Aoyama, Hiroshi

experimental part, p. 5323 - 5338 (2010/09/15)

A novel series of tryptase inhibitors with a N-phenylphthalimide skeleton structurally derived from thalidomide (1) has been developed. Structure-activity relationship studies led to a potent and selective tryptase inhibitor, 2-(4-cyanophenyl)isoindole-1,3-dione-5-yl 3-(2-aminopyridin-5-yl)propanoate (7), with the IC50 value of 78 nM.
