The CAS Registry Mumber 177203-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,7,2,0 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 177203-77:
(8*1)+(7*7)+(6*7)+(5*2)+(4*0)+(3*3)+(2*7)+(1*7)=139
139 % 10 = 9
So 177203-77-9 is a valid CAS Registry Number.

Photolysis of fluorodiphenylamines

Groundwater, Paul W.,Hughes, David,Hursthouse, Michael B.,Lewis, Rhiannon

, p. 669 - 673 (2007/10/03)

Photolysis of 2-fluoro-2′,5′-dimethyldiphenylamine 1a, in ethanol with a medium-pressure mercury lamp, gave a mixture of 1,4-dimethylcarbazole 7 (53%), 8-fluoro-1,4-dimethylcarbazole 2 (11%) and 6-ethoxy-2-fluoro-2′,5′-dimethyldiphenylamine 8 (19%). Photolysis of 4-fluoro-2′,5′-dimethyldiphenylamine 1b gave 6-fluoro-1,4-dimethylcarbazole 25 (35%) and 1,4-dimethylcarbazole 7 (47%).
