Check Digit Verification of cas no

The CAS Registry Mumber 31250-13-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,2,5 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 31250-13:
(7*3)+(6*1)+(5*2)+(4*5)+(3*0)+(2*1)+(1*3)=62
62 % 10 = 2
So 31250-13-2 is a valid CAS Registry Number.

Monocyclic macrocyclic compounds and complexes thereof

-

, (2008/06/13)

Novel monocyclic macrocyclic compounds having nitrogen bridgehead atoms and having in the hydrocarbon bridging chains at least two additional hetero atoms selected from the group consisting of sulfur, oxygen, and nitrogen, when admixed with a compatible cation-donor compound form stable cation-containing macrocyclic complexes which, in turn, can be conveniently dissociated by addition of acid or a quaternizing agent. The novel macrocyclics are valuable for use in the same way and for the same purposes as chelating agents.
