122993-63-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 122993-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,9,9 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 122993-63:
(8*1)+(7*2)+(6*2)+(5*9)+(4*9)+(3*3)+(2*6)+(1*3)=139
139 % 10 = 9
So 122993-63-9 is a valid CAS Registry Number.

Synthesis and Mass Spectrometric Fragmentation of Dihydroisoindole Derivatives

Knefeli, Frank,Mayer, Klaus K.,Wiegrebe, Wolfgang

, p. 419 - 426 (2007/10/02)

C-8-substituted N-methyl-1,2,3,4-tetrahydroisoquinoline radical cations lose the complete substituent in a one step reaction giving rise to an unexpected ion at m/z 146, which is probably identical with the dihydroisoindolylmethyl-cation A.The dihydroisoindoles 1, 10, and 16 were prepared as potentially alternative precursors of ion A.Hovever, the ion at m/z 146 in their EI mass spectra is of very low intensity, so CID-experiments for structural comparison could not be performed.The electron impact induced fragmentations of 1, 10, and 16 are discussed.
