4017-81-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4017-81-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,1 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4017-81:
(6*4)+(5*0)+(4*1)+(3*7)+(2*8)+(1*1)=66
66 % 10 = 6
So 4017-81-6 is a valid CAS Registry Number.

Formation of 1,2-Dioxolanes from Cyclopropanes
Ruecker, Gerhard,Frey, Klaus
, p. 389 - 392 (2007/10/02)
The already known carenols 5 and 7 are obtained by stereoselective oxirane cleavage of (1S,3S,4R,6R)-(+)-3α,4α-epoxycarane (4).Autoxidation of the ketone 8, derived from 7, failed to give any 1,2-dioxolane derivatives. 5 is converted to the hydroperoxide
