Check Digit Verification of cas no

The CAS Registry Mumber 21825-18-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,2 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21825-18:
(7*2)+(6*1)+(5*8)+(4*2)+(3*5)+(2*1)+(1*8)=93
93 % 10 = 3
So 21825-18-3 is a valid CAS Registry Number.

Oxanilic acids, a new series of orally active antiallergic agents

Sellstedt,Guinosso,Begany,Bell,Rosenthale

, p. 926 - 933 (2007/10/05)

A large number of oxanilic acid esters and N heteroaryl oxamic acid esters were prepared and found to have antiallergic activity using the rat passive cutaneous anaphylaxis (PCA) test. Many of the oxanilic acid esters are active orally, with the most active species having an aryl 2' carbamoyl group and a 3' methoxy group. Hydrolysis of the ester from the oxanilic ester moiety causes a loss of oral activity.
