Check Digit Verification of cas no
The CAS Registry Mumber 134142-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,1,4 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134142-89:
(8*1)+(7*3)+(6*4)+(5*1)+(4*4)+(3*2)+(2*8)+(1*9)=105
105 % 10 = 5
So 134142-89-5 is a valid CAS Registry Number.

Photoreductive cleavage of Phenyl-Selenium Bonds of Phenylselenoalkanes.
Ferritto, Rafael,Vogel, Pierre
, p. 1193 - 1196 (2007/10/02)
Photo-induced-electron transfer from triethylamine to phenylselenoalkanes can lead to selective reduction and cleavage of the Ph-Se bond leading to the formation of benzene and the corresponding alkylselenyl radicals that dimerize.
