Check Digit Verification of cas no
The CAS Registry Mumber 20261-24-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,6 and 1 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20261-24:
(7*2)+(6*0)+(5*2)+(4*6)+(3*1)+(2*2)+(1*4)=59
59 % 10 = 9
So 20261-24-9 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.
