Check Digit Verification of cas no
The CAS Registry Mumber 129957-20-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,9,5 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129957-20:
(8*1)+(7*2)+(6*9)+(5*9)+(4*5)+(3*7)+(2*2)+(1*0)=166
166 % 10 = 6
So 129957-20-6 is a valid CAS Registry Number.

Three-Step Synthesis of Fluoranthenes through Pd-Catalyzed Inter- and Intramolecular C-H Arylation
Yamaguchi, Miyuki,Higuchi, Mayu,Tazawa, Kanae,Manabe, Kei
, p. 3967 - 3974 (2016)
A three-step synthetic method for the preparation of fluoranthenes, involving Miura's intermolecular C-H arylation, nonaflation, and intramolecular C-H arylation, has been developed. Various 1-naphthols and haloarenes were successfully used as substrates. Reaction conditions that afford high site selectivity have been developed for the intramolecular C-H arylation step.
