Check Digit Verification of cas no
The CAS Registry Mumber 17980-16-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,8 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 17980-16:
(7*1)+(6*7)+(5*9)+(4*8)+(3*0)+(2*1)+(1*6)=134
134 % 10 = 4
So 17980-16-4 is a valid CAS Registry Number.

Oxidative, Iodoarene-Catalyzed Intramolecular Alkene Arylation for the Synthesis of Polycyclic Aromatic Hydrocarbons
Zhao, Zhensheng,Britt, Liam H.,Murphy, Graham K.
, p. 17002 - 17005 (2018/11/01)
A catalytic, metal-free and chemoselective oxidative intramolecular coupling of arene and alkene C?H bonds is reported. The active hypervalent iodine (HVI) reagent, generated catalytically in situ from iodotoluene and meta-chloroperoxybenzoic acid (m-CPBA), reacts with o-vinylbiphenyls to generate polyaromatic hydrocarbons in up to 95 % yield. Experimental evidence suggests the reactions proceed though vinyliodonium and, possibly, vinylenephenonium intermediates.
