134792-79-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134792-79-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,7,9 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134792-79:
(8*1)+(7*3)+(6*4)+(5*7)+(4*9)+(3*2)+(2*7)+(1*9)=153
153 % 10 = 3
So 134792-79-3 is a valid CAS Registry Number.

Substituent control in the synthesis of tetrahydropyrans, oxepanes and oxocanes by episulphonium ion-mediated cyclisation
Lopez-Tudanca,Jones,Brownbridge
, p. 2261 - 2264 (2007/10/02)
Cyclisation of the heptenols (1), (6a), (6b), and (6c) to cyclic ethers via episulphonium ions has been studied and the effect of allylic substituents on the size of ring produced has been explored.
