109123-32-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109123-32-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,1,2 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 109123-32:
(8*1)+(7*0)+(6*9)+(5*1)+(4*2)+(3*3)+(2*3)+(1*2)=92
92 % 10 = 2
So 109123-32-2 is a valid CAS Registry Number.

Ambifunctional Reactivity of 3-Trifloxypropeniminium Salts Towards Nucleophiles
Singer, Berndt,Maas, Gerhard
, p. 1683 - 1690 (2007/10/02)
Reaction of 3-trifloxypropeniminium salts 1 with nucleophiles may occur at carbon atoms C-1 or C-3.Hydrolysis of 1a-e leads to β-formylvinyl triflates 2 preferentially.The trifloxy group at C-3 is substituted in most cases by sulfur or nitrogen nucleophil
