Check Digit Verification of cas no
The CAS Registry Mumber 128924-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,2 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128924-91:
(8*1)+(7*2)+(6*8)+(5*9)+(4*2)+(3*4)+(2*9)+(1*1)=154
154 % 10 = 4
So 128924-91-4 is a valid CAS Registry Number.

Accelerating water exchange for GDIII chelates by steric compression around the water binding site
Ruloff, Robert,Toth, Eva,Scopelliti, Rosario,Tripier, Raphael,Handel, Henri,Merbach, Andre E.
, p. 2630 - 2631 (2007/10/03)
The water exchange process was accelerated for nine-coordinate, monohydrated macrocyclic GdIII complexes by inducing steric compression around the water binding site; the increased steric crowding was achieved by replacing an ethylene bridge of
