Check Digit Verification of cas no

The CAS Registry Mumber 181589-83-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,5,8 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 181589-83:
(8*1)+(7*8)+(6*1)+(5*5)+(4*8)+(3*9)+(2*8)+(1*3)=173
173 % 10 = 3
So 181589-83-3 is a valid CAS Registry Number.

Zr-E π-bonding in complexes derived from E-H additions to Cp2Zr(P(C6H2-2,4,6-t-Bu3))(PMe 3)

Breen, Tricia L.,Stephan, Douglas W.

, p. 4223 - 4227 (1996)

Additions of PhEH (E = O, S), PhEH2 (E = N, P), MesPH2, and Ph2PH to Cp2Zr(PR*)-(PMe3) (2) provide a facile route to complexes of the form Cp2Zr(PHR*)(ER) (R* = 2,4,6-t-Bu-C6H2; ER = OPh (3), SPh (4), NHPh (5), PHPh (6), PHMes (7), PPh2 (8)). Variabletemperature NMR studies are consistent with facile metal-mediated inversion at phosphorus as well as rapid rotation about the Zr-E bonds at room temperature.
