Check Digit Verification of cas no

The CAS Registry Mumber 139219-53-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,1 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139219-53:
(8*1)+(7*3)+(6*9)+(5*2)+(4*1)+(3*9)+(2*5)+(1*3)=137
137 % 10 = 7
So 139219-53-7 is a valid CAS Registry Number.

Preparation and some properties of chiral ansa-mono(η5-fluorenyl)zirconium(IV) complexes

Rieger, Bernhard

, p. C17 - C20 (2007/10/02)

Symmetrically-substituted epoxides react with fluorenyllithium to give the corresponding alcohols in high yields.These were used to prepare ansa-bridged mono(η5-fluorenyl)-zirconium complexes of the general formula ZrCl2(thf)2 (CHR-CHR=cyclohexyl, cyclopentyl, 1,2-diphenylethyl).With Al(CH3)3 as cocatalyst these complexes catalyze the polymerization of ethene.
