Check Digit Verification of cas no

The CAS Registry Mumber 15602-41-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,6,0 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15602-41:
(7*1)+(6*5)+(5*6)+(4*0)+(3*2)+(2*4)+(1*1)=82
82 % 10 = 2
So 15602-41-2 is a valid CAS Registry Number.

The reaction of hexacarbonylvanadium with aromatic compounds. III. Reduction of the [V(CO)4arene]+ cations to tetracarbonyl-π-cyclohexadienylvanadium derivatives

Calderazzo, Fausto

, p. 429 - 434 (2008/10/08)

The hexacarbonylvanadate of the [V(CO)4C6H6]+ cation reacts with sodium tetrahydridoborate to give the red crystalline volatile V(CO)4C6H7 in about 60% yield. On the basis of infrared and nmr data this is shown to be tetracarbonyl-π-cyclohexadienylvanadium. Methyl-substituted cyclohexadienyl compounds V(CO)4C6H7-n(CH3)n are also described, being obtained by reduction of the methyl-substituted arene vanadium compounds [V(CO)4C6H6-n(CH3)n] +. Similar reactions with NaBD4 yielded the corresponding deuterated compounds. The nmr spectra suggest that the addition of hydrogen occurs preferentially at unsubstituted positions of the aromatic ring in [V(CO)4C6H6-n(CH3)n] +. The type of bonding between the metal and the cyclohexadienyl system and the conformation of the cyclohexadienyl ligand are briefly discussed.
