Check Digit Verification of cas no
The CAS Registry Mumber 117221-81-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,2,2 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 117221-81:
(8*1)+(7*1)+(6*7)+(5*2)+(4*2)+(3*1)+(2*8)+(1*1)=95
95 % 10 = 5
So 117221-81-5 is a valid CAS Registry Number.

14. The Adamantane Rearrangement of Tricyclo1,5>decane to Tricyclo4,8>decane
Ghatak, Kanai L.,Ganter, Camille
, p. 124 - 129 (2007/10/02)
Regioselective generation of the C(2)-carbocation a of tricyclo1,5>decane (1) by treatment of both corresponding epimeric alcohols 5 and 6 with BF3 and trapping the rearranged tricyclo4,8>decan-7-yl carbocation b with Et3SiH as hydride-ion donor (ionic hydrogenation) gives the corresponding hydrocarbon 3 as sole product in almost quantitative yield.The latter is a known intermediate in the Lewis-acid-catalyzed rearrangement of 1 to adamantane (4).
