89243-61-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89243-61-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,2,4 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89243-61:
(7*8)+(6*9)+(5*2)+(4*4)+(3*3)+(2*6)+(1*1)=158
158 % 10 = 8
So 89243-61-8 is a valid CAS Registry Number.

Synthesis and Dynamic Behaviour of Pentamethylcyclopentadienylphosphanes
Jutzi, Peter,Saleske, Hartmut
, p. 222 - 233 (2007/10/02)
By reaction of pentamethylcyclopentadienyl(Me5cp)-lithium with halogenophosphanes the Me5cp-phosphanes 1 - 5, 7, 8, 11, 12, 14, 15, and 19 - 24 are synthesized.Substitution reactions with the Me5cp-halogenophosphanes 7 and 14 lead to the Me5cp-phosphanes
