22472-81-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 22472-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,4,7 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22472-81:
(7*2)+(6*2)+(5*4)+(4*7)+(3*2)+(2*8)+(1*1)=97
97 % 10 = 7
So 22472-81-7 is a valid CAS Registry Number.

The synthesis of 1,8-cineoles. the origin of the oxygen atom
Brecknell, Douglas J.,Carman, Raymond M.,Garner, A. Christopher
, p. 35 - 41 (2007/10/03)
1,8-Cineoles can be synthesized by ring closure of p-menthane precursors carrying the potential ether oxygen atom on either C1 or C8. Comparisons are made between these two routes.
