Check Digit Verification of cas no

The CAS Registry Mumber 170728-43-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,7,2 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 170728-43:
(8*1)+(7*7)+(6*0)+(5*7)+(4*2)+(3*8)+(2*4)+(1*3)=135
135 % 10 = 5
So 170728-43-5 is a valid CAS Registry Number.

BILE ACID CONJUGATES, DERIVATIVES THEREOF WITH METAL COMPLEXES AND RELATED USES

-

, (2008/06/13)

Novel paramagnetic metal ion chelates and their use as contrast agents in the diagnostic technique known as "magnetic resonance imaging" (M.R.I.) of the gastrointestinal tract and particularly of the liver, are described. The novel compounds result from the conjugation of a bile acid with a chelating agent and are capable of chelating the ions of bivalent and trivalent metals. The compounds have formula A-L-B in which A is the residue of a bile acid and derivatives of a bile acid, B is the residue of a chelating agent of a bivalent or trivalent metal ion having an atomic number of 20 to 31, 39, 42, 43, 44, 49, 57 to 83, L is a ligand between A and B.
