Check Digit Verification of cas no
The CAS Registry Mumber 64977-49-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,9,7 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 64977-49:
(7*6)+(6*4)+(5*9)+(4*7)+(3*7)+(2*4)+(1*9)=177
177 % 10 = 7
So 64977-49-7 is a valid CAS Registry Number.

Domino synthesis of fluorine-substituted polycyclic aromatic hydrocarbons: 1,1-difluoroallenes as synthetic platforms
Fuchibe, Kohei,Mayumi, Yuka,Zhao, Nan,Watanabe, Shumpei,Yokota, Misaki,Ichikawa, Junji
supporting information, p. 7825 - 7828 (2013/08/23)
Rather crafty: 1,1-Difluoroallenes bearing an aryl group and a cyclopentene moiety undergo indium(III)-catalyzed Friedel-Crafts-type cyclization with subsequent ring expansion and dehydrogenation to afford fluorinated polycyclic aromatic hydrocarbons in high yields. The introduction of an Ar group was effected by in situ halogenation of the intermediary indium species and a subsequent Suzuki-Miyaura reaction. Copyright
