191803-23-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 191803-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,8,0 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 191803-23:
(8*1)+(7*9)+(6*1)+(5*8)+(4*0)+(3*3)+(2*2)+(1*3)=133
133 % 10 = 3
So 191803-23-3 is a valid CAS Registry Number.

-
Page/Page column 16, (2011/11/13)
A method of synthesizing an alkyl cyclopentadiene compound is disclosed. The method includes contacting at least one cyclopentadienyl anion source and at least one alkyl group source to form at least one alkyl cyclopentadiene compound. The method further includes extracting the alkyl cyclopentadiene compound with a hydrocarbon solvent. The alkyl cyclopentadiene compound may be converted to a metallocene catalyst compound.
