Check Digit Verification of cas no
The CAS Registry Mumber 75181-08-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,1,8 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 75181-08:
(7*7)+(6*5)+(5*1)+(4*8)+(3*1)+(2*0)+(1*8)=127
127 % 10 = 7
So 75181-08-7 is a valid CAS Registry Number.

(C5Me5)SiMe3 as a mild and effective reagent for transfer of the C5Me5 ring: an improved route to monopentamethylcyclopentadienyl trihalides of the group 4 elements
Llinas, Gerardo Hidalgo,Mena, Miguel,Palacios, Federico,Royo, Pascual,Serrano, Ricardo
, p. 37 - 40 (2007/10/02)
The reaction between (C5Me5)SiMe3 and group 4 element tetrahalides MX4 (M=Ti, X=Cl, Br, I; M=Zr and Hf, X=Cl) gives the corresponding (η5-C5Me5)MX3 derivatives in nearly quantitative yields in a one-step procedure without the need for further purification.
