68211-44-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 68211-44-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,2,1 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 68211-44:
(7*6)+(6*8)+(5*2)+(4*1)+(3*1)+(2*4)+(1*4)=119
119 % 10 = 9
So 68211-44-9 is a valid CAS Registry Number.

Stereoselectivity in the Formation and Allylic Rearrangement of 8a-Methyl- and 8a-Ethyl-1,2,3,4,4a,7,8,8a-octahydronaphthalenyl Hydroperoxides

Avila, David V.,Davies, Alwyn G.,Davison, Ian G. E.

, p. 1847 - 1852 (2007/10/02)

4a-Methyl- and 4a-ethyl-1,2,3,4,4a,5,6,7-octahydronaphthalene have been subjected to singlet oxygen oxygenation, and the various hydroperoxides which are formed have been characterised.Evidence is presented that the 8aβ-alkyl-1,2,3,4,4a,7,8,8a-octahydronaphthalen-4aα-yl hydroperoxides (I; R=Me or Et) rearrange suprafacially and irreversibly in chloroform at 25 deg C to give only the 4aβ-alkyl-2,3,4,4a,5,6,7,8-octahydronaphthalen-2α-yl hydroperoxides (II).Under the same conditions, the corresponding 8aβ-alkyl-1,2,3,4,4a,7,8,8a-octahydronaphthalen-4aβ-yl hydroperoxides rearrange much more slowly.
