Check Digit Verification of cas no
The CAS Registry Mumber 70969-28-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,9,6 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 70969-28:
(7*7)+(6*0)+(5*9)+(4*6)+(3*9)+(2*2)+(1*8)=157
157 % 10 = 7
So 70969-28-7 is a valid CAS Registry Number.

Zirconium complexes of a cross-bridged cyclam
O'Connor, Paul,Berg, David J.,Twamley, Brendan

The acid-base reaction of tetrabenzylzirconium with 1,4,8,11-tetraazabicyclo[6.6.2]-hexadecane (H2(CBC), 1) produces (CBC)Zr(CH2Ph)2, 2. Similarly, reaction of 2 with phenols yields (CBC)Zr(CH2Ph)(O-2, 6-C6H3Bu 2t), 3, and (CBC)Zr(O-2,6-C6H 3Me2)2, 5. Prolonged heating of 3 leads to the metalated product (CBC)Zr[k2(C,O)-OC6H 3(6-But)(2-CMe2CH2)], 4. Reaction of ZrCl2[N(SiMe3)3]2 with H 2(CBC) leads to (CBC)ZrCl2, 6, which subsequently affords (CBC)Zr(X)(Y) by salt metathesis (7, X = Cl, Y = N(SiMe3) 2; 8, X = Y = CH3; 9, X = Y = CH2Si(CH 3)3). Compounds 3 and 7 show restricted rotation about the Zr-O and Zr-N bonds, respectively, on the NMR time scale. For 3, the energy of activation for this process was determined to be 69 ±1 kJ/mol. Neither 6 nor 8 shows ethylene polymerization activity when treated with 500 equiv of MAO. Reaction of 6 with 2 equiv of n-BuLi in the presence of excess diphenylacetylene leads to the zirconacyclopentadiene 10, (CBC)Zr(C 4Ph4). The structures of 5, 9, and 10 have been determined by X-ray crystallography, and all three display distorted octahedral geometry.
