1202640-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1202640-33-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,6,4 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1202640-33:
(9*1)+(8*2)+(7*0)+(6*2)+(5*6)+(4*4)+(3*0)+(2*3)+(1*3)=92
92 % 10 = 2
So 1202640-33-2 is a valid CAS Registry Number.

Aluminium triflate catalysed cyclisation of unsaturated alcohols: novel synthesis of rose oxide and analogues
Coulombel, Lydie,Weiwer, Michel,Dunach, Elisabet
experimental part, p. 5788 - 5795 (2010/03/03)
Aluminium trifluoromethanesulfonate was used as an efficient catalyst for the cycloisomerisation of several unsaturated alcohols into cyclic ethers such as rose oxide and some of its ether analogues.
