Check Digit Verification of cas no
The CAS Registry Mumber 66657-91-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,6,5 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 66657-91:
(7*6)+(6*6)+(5*6)+(4*5)+(3*7)+(2*9)+(1*1)=168
168 % 10 = 8
So 66657-91-8 is a valid CAS Registry Number.

(Chemical Equation Presented) o-Alkenyl or alkynyl benzylzirconocene intermediate, which was readily generated by the reaction of 2-alkoxymethyl-styrene or 2-alkoxymethyl-1-(trimethylsilylethynyl)-benzene derivative with zirconocene-butene complex (Negishi reagent, "Cp 2Zr"), reacted with allyl or propargyl halides in the presence of a catalytic amount of CuCl to give allylation or allenylation products. Conversion to Dane's diene, which is a key intermediate for estrone synthesis, was efficiently carried out by enyne olefin metathesis of the allylation products.
