87064-17-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87064-17-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,0,6 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87064-17:
(7*8)+(6*7)+(5*0)+(4*6)+(3*4)+(2*1)+(1*7)=143
143 % 10 = 3
So 87064-17-3 is a valid CAS Registry Number.

Application of intramolecular D?tz reaction to the synthesis of ansa-compounds: concise synthesis of arnebinol
Watanabe, Masahito,Tanaka, Kyosuke,Saikawa, Yoko,Nakata, Masaya
, p. 203 - 206 (2007/10/03)
Fischer carbene complexes having long alkynyloxy chains regioselectively produced oxametacyclophanes via the intramolecular D?tz reaction. The utility of this reaction was demonstrated in the synthesis of arnebinol, an ansa-type terpenoid, from geranyl acetate in six steps.
