858098-20-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 858098-20-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,8,0,9 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 858098-20:
(8*8)+(7*5)+(6*8)+(5*0)+(4*9)+(3*8)+(2*2)+(1*0)=211
211 % 10 = 1
So 858098-20-1 is a valid CAS Registry Number.

Page/Page column 14-15, (2008/06/13)
The present invention provides a method of making fulvenes, particularly 6-aryl-6-alkylfulvenes, 6-aryl-6-alkenylfulvenes, and related compounds, by combining alkyl- or alkenyl-arylketones with magnesium cyclopentadienyl reagents in nonprotic, including e
