Check Digit Verification of cas no

The CAS Registry Mumber 89352-55-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,3,5 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 89352-55:
(7*8)+(6*9)+(5*3)+(4*5)+(3*2)+(2*5)+(1*5)=166
166 % 10 = 6
So 89352-55-6 is a valid CAS Registry Number.

1-PYRAZOLYLIRIDIUM(I) DERIVATIVES; X-RAY EVIDENCE FOR MONODENTATE PYRAZOLATO LIGANDS

Bandini, Anna Laura,Banditelli, Guido,Bonati, Flavio,Demartin, Francesco,Manassero, Mario,Minghetti, Giovanni

, p. C9 - C11 (1982)

An X-ray crystal structure determination has shown that trans-(Ph3P)2Ir(CO)(pyrazolato-N), obtained from the chloride and potassium pyrazolate, contains a monodentate azolato ligand.

A SERIES OF MONOHAPTO PYRAZOLATES OF IRIDIUM(I) AND IRIDIUM(III)

Bandini, Anna Laura,Banditelli, Guido,Bonati, Flavio,Minghetti, Giovanni,Demartin, Francesco,Manassero, Mario

, p. 91 - 106 (2007/10/02)

The reaction of trans-IrCl(CO)L2 with pz-* gives trans-Ir(pz-N)(CO)L2, where pzH is 3,5-dimethyl-, 3,5-dimethyl-4-nitro- or 3,5-bis(trifluoromethyl)-pyrazole, and L = PPh3.The nitrogen atom not involved in coordination can be protonated with HBF4 to give the corresponding + cation.The iridium(I) pyrazolates undergo oxidative addition, yielding Ir(H)2(pz-N)(CO)L2 species, while gaseous HCl cleaves the Ir-N bond, affording IrH(Cl)2(CO)L2.The iridium(I) derivatives can be obtained in several solid-state forms, each characterized by a slightly different CO stretching frequency.The presence of a monodentate pyrazolato ligand in trans-Ir(3,5-(CF3)2pz-N)(CO)L2, in the form with ν(CO) at 1975 cm-1, is supported also by an X-ray crystal structure determination.The compound crystallizes in the monoclinic system, space group P21/n, with cell dimensions a = 21.106(6), b = 19.700(5), c = 9.437(2) Angstroem, and β = 94.34(2) deg and Z = 4.
