103216-80-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 103216-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,2,1 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 103216-80:
(8*1)+(7*0)+(6*3)+(5*2)+(4*1)+(3*6)+(2*8)+(1*0)=74
74 % 10 = 4
So 103216-80-4 is a valid CAS Registry Number.

SYNTHESIS AND THERMAL REACTIONS OF 3-TRIMETHYLSILYL-1-PYRAZOLINE

Conlin, Robert T.,Kwak, Young-Woo

, p. 177 - 184 (1985)

The compound 3-trimethylsilyl-1-pyrazoline has been synthesized by addition of diazomethane to vinyltrimethylsilane at room temperature.In contrast, addition of trimethylsilyldiazomethane to ethylene at 55 deg C yields 1-trimethylsilyl-2-pyrazoline exclusively.The thermal isomerization of 3-trimethylsilyl-1-pyrazoline to 1-trimethylsilyl2-pyrazoline has been followed kinetically by proton NMR spectroscopy and the reverse reaction has been detected by gas phase pyrolysis.Thermal elimination of nitrogen from either pyrazoline leads to cyclopropyltrimethylsilane, allyltrimethylsilane and E- and Z-1-propenyltrimethylsilane.The relative rates of methylene-H migration to radical centers α and γ to silicon are approximately equal.
