Check Digit Verification of cas no

The CAS Registry Mumber 128594-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,9 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128594-25:
(8*1)+(7*2)+(6*8)+(5*5)+(4*9)+(3*4)+(2*2)+(1*5)=152
152 % 10 = 2
So 128594-25-2 is a valid CAS Registry Number.

Darstellung und Eingenschaften von und Reaktionen mit metallhaltigen Heterocyclen LXX. Untersuchungen ueber den Zusammenhang zwischen Konformation und chemischer Verschiebung in Phosphametallacycloalkanen

Lindner, Ekkehard,Fawzi, Riad,Mayer, Hermann A.,Eichele, Klaus,Pohmer, Klaus

, p. 63 - 77 (1990)

To investigate the well known dependence of 31P NMR chemical shift values on the ring size of phosphametallacycloalkanes, we compared the series of cyclic and acyclic complexes, Br(OC)4MnPPh2(CH2)nH (1a-1d), (η5-C5H5)Cl(OC)2WPPh2(CH2)nH (2a-2c), (η5-C5H5)Me(OC)2WPPh2(CH2)nH (3a-3c), (4b-4d), (5b,5c) (n=2 (a), 3 (b), 4 (c), 5 (d)).Different conformations have an obvious influence on the 31P and 13C chemical shift of metal adjacent ring atoms.The structure of phosphawolframacyclopentane (5b) in solution differs from the crystaline state.
