Calculate Digit Verification of CAS Registry Number 69769-82:
(7*6)+(6*9)+(5*7)+(4*6)+(3*9)+(2*8)+(1*2)=200
200 % 10 = 0
So 69769-82-0 is a valid CAS Registry Number.

Photolysis of Some ortho-Methylated Monochlorobiphenyls

Bunce, Nigel J.,DeSchutter, Connie T.,Toone, Eric J.

, p. 859 - 862 (2007/10/02)

A series of monochloro-o-methylated biphenyls was photolysed.Quantum yields of dechlorination lie in between the low values observed for 3- and 4-chlorobiphenyl and the high values obtained for 2-chlorobiphenyl.The results are interpreted in terms of raising the energy of the excited state due to steric crowding of the ortho-substituent and relief of strain upon the departure of an ortho-chlorine.
