Check Digit Verification of cas no
The CAS Registry Mumber 207744-04-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,7,4 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 207744-04:
(8*2)+(7*0)+(6*7)+(5*7)+(4*4)+(3*4)+(2*0)+(1*4)=125
125 % 10 = 5
So 207744-04-5 is a valid CAS Registry Number.

Novel thieno[2,3-d][1,3]oxazin-4-ones as inhibitors of human leukocyte elastase
Gütschow, Michael,Neumann, Ulf
, p. 1729 - 1740 (2007/10/03)
A series of thieno[2,3-d][1,3]oxazin-4-ones was synthesized and evaluated in vitro for inhibitory activity toward human leukocyte elastase. New synthetic routes to 2-alkoxy-, 2-alkylthio-, and 2-sec-amino-substituted derivatives are reported. This study d
