Check Digit Verification of cas no

The CAS Registry Mumber 261178-91-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,1,1,7 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 261178-91:
(8*2)+(7*6)+(6*1)+(5*1)+(4*7)+(3*8)+(2*9)+(1*1)=140
140 % 10 = 0
So 261178-91-0 is a valid CAS Registry Number.

Amino acid and peptide derivatives as antiallergic and anti-inflammatory agents

Shalaby,El-Sawy,El-Salam, O. I. Abd,Abdullah,Elshihaby, Soha A.

experimental part, p. 807 - 821 (2012/08/07)

It was proved that current anti-allergic drugs comprise piperazine - and acrylic acid segments. These compounds were structurally designed as 5-lipoxygenase inhibitors depending on two action mechanisms of the ready drugs used to treat allergy e.g. (Oxatomide), which contains piperazine moiety, its anti-allergic effects possess antagonist activities against chemical mediators such as histamine, Serotonine and leukotriencs (which cause allergy). Also, (Tranilast), which contains acrylic acid segment; its activity depends on inhibition of mediator release. In harmony with these findings new structures having anti-allergic properties are proposed in this manuscript. New products, (5a-u) with expected better biological activities and decreased side effects were synthesized by the addition of an amino acid conjugate of cinnamic acid to a piperazine segment. Their antiallergic and anti-inflammatory activities were evaluated. Most of them show promising activities.
