1696-25-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1696-25-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,9 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1696-25:
(6*1)+(5*6)+(4*9)+(3*6)+(2*2)+(1*5)=99
99 % 10 = 9
So 1696-25-9 is a valid CAS Registry Number.

Formation of secondary ozonides in the gas phase low-temperature ozonation of primary and secondary alkenes

Fajgar, Radek,Vitek, Josef,Haas, Yehuda,Pola, Josef

, p. 239 - 248 (2007/10/03)

The gas-phase ozonation of a series of alkenes RCH=CH2 (R = Et, Hex), trans-RHC=CHR (R = Me, Et, Pri) and Me2C=CMe2 at -40 to 20°C, and that of ethene H2C=CH2 at -120 to 0°C at 10-4 v/v concentrations in N2 at atmospheric pressure have been studied. Using complementary product analysis by means of GC-FTIR and GC-MS techniques, we present conclusive evidence for the formation of secondary alkene ozonides as high-yield products in all instances except Me2C=CMe2. It is shown that the stereoselectivity for the conversion of trans-RHC=CHR (R = Me, Et, Pri) to trans-secondary ozonides in the gas phase is similar to that observed earlier in solution, and that the yields of secondary ozonides from RHC=CH2, but not those from RHC=CHR, significantly decrease with increasing temperature.
