The CAS Registry Mumber 138816-09-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,1 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138816-09:
(8*1)+(7*3)+(6*8)+(5*8)+(4*1)+(3*6)+(2*0)+(1*9)=148
148 % 10 = 8
So 138816-09-8 is a valid CAS Registry Number.

Corannulene. A three-step synthesis

Scott, Lawrence T.,Cheng, Pei-Chao,Hashemi, Mohammed M.,Bratcher, Matthew S.,Meyer, Dayton T.,Warren, Hope B.

, p. 10963 - 10968 (2007/10/03)

Thermal cyclization of 7,10-diethynylfluoranthene (3) in the gas phase gives corannulene (2), the smallest bowl-shaped polycyclic hydrocarbon fragment of C60 with fullerene-like curvature. Bromocorannulene (10) and 1,6-dibromocorannulene (9) have also been obtained from flash pyrolysis of 7,10-bis(2,2-dibromovinyl)fluoranthene (8). Short, practical syntheses of several corannulene precursors from acenaphthenequinone are described which have made corannulene available in gram quantities.
