Check Digit Verification of cas no

The CAS Registry Mumber 133190-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,1,9 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 133190-48:
(8*1)+(7*3)+(6*3)+(5*1)+(4*9)+(3*0)+(2*4)+(1*8)=104
104 % 10 = 4
So 133190-48-4 is a valid CAS Registry Number.

Preparation and crystal structures of the complexes (η5-C5H3Me-CMe2-η5-C13H8)MCl2 (M=Zr or Hf): mechanistic aspects of the catalytic formation of a syndiotactic-isotactic stereoblock-type polypropylene

Razavi, Abbas,Atwood, Jerry L.

, p. 105 - 112 (2007/10/02)

The reaction of MCl4 (M=Zr or Hf) with the dilithium salt of 2-methyl-3-cyclopentadienyl-2-fluorenylpropane in pentane leads to the formation of the complexes (η5-C5H3Me)-CMe2-η5-C13H8)MCl2.NMR and X-ray diffraction data show that the fluorenyl groups are η5 bonded in these complexes.When activated with methylaluminoxane or other appropriate ionizing agents, both complexes catalyze the polymerization of propylene in a di-stereospecific manner, to give syndiotactic-isotactic stereoblock polypropylene.Keywords: Zirconium; Hafnium; NMR spectroscopy; Crystal structure
