Check Digit Verification of cas no

The CAS Registry Mumber 205126-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,1,2 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 205126-80:
(8*2)+(7*0)+(6*5)+(5*1)+(4*2)+(3*6)+(2*8)+(1*0)=93
93 % 10 = 3
So 205126-80-3 is a valid CAS Registry Number.

Benzimidazole receptors for carboxylic acids

Almaraz, Marta,Martin, Mercedes,Hernandez, Jose V.,Caballero, Ma. Cruz,Moran, Joaquin R.

, p. 1811 - 1814 (1998)

Combination of an aminobenzimidazole with a chromenone unit provides a receptor for carboxylic acids or primary amides. This host is highly selective for carboxylic acids with K(ass) above 106 M-1 while amides only bind weakly with association constant sin the order of hundreds of M-1.
