158693-69-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158693-69-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,6,9 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 158693-69:
(8*1)+(7*5)+(6*8)+(5*6)+(4*9)+(3*3)+(2*6)+(1*9)=187
187 % 10 = 7
So 158693-69-7 is a valid CAS Registry Number.

ADDITION OF ARENESELENENYL HALIDES TO α,β-UNSATURATED SULFONES
Mannafov, T. G.,Berdnikov, E. A.,Tantasheva, F. R.
, p. 77 - 80 (2007/10/02)
The addition of areneselenenyl halides to aryl vinyl sulfones and ethynyl p-tolyl sulfone was investigated.By analysis of the PMR spectra of the obtained compounds and their chemical transformations it was established that the addition was regiospecific a
