5208-31-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5208-31-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,0 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5208-31:
(6*5)+(5*2)+(4*0)+(3*8)+(2*3)+(1*1)=71
71 % 10 = 1
So 5208-31-1 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
