Check Digit Verification of cas no

The CAS Registry Mumber 298698-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,8,6,9 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 298698-90:
(8*2)+(7*9)+(6*8)+(5*6)+(4*9)+(3*8)+(2*9)+(1*0)=235
235 % 10 = 5
So 298698-90-5 is a valid CAS Registry Number.

scheme or table, p. 2766 - 2771 (2009/12/31)

A series of phenothiazine carboxylic acid derivatives, having 6-amino-pyrimidine-2,4(1H,3H)-dione moiety via a appropriate linker, were synthesized and evaluated for their affinity toward human histamine H1 receptor and Caco-2 cell permeability. Selected compounds were further evaluated for their oral anti-histaminic activity in mice and bioavailability in rats. Finally, promising compounds were examined for their anti-inflammatory potential in mice OVA-induced biphasic cutaneous reaction model. Among the compounds tested, phenothiazineacetic acid compound 27 showed both histamine H1-receptor antagonistic activity and anti-inflammatory activity in vivo model.
