Check Digit Verification of cas no

The CAS Registry Mumber 1394136-65-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,4,1,3 and 6 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1394136-65:
(9*1)+(8*3)+(7*9)+(6*4)+(5*1)+(4*3)+(3*6)+(2*6)+(1*5)=172
172 % 10 = 2
So 1394136-65-2 is a valid CAS Registry Number.

Scalable synthesis of quaterrylene: Solution-phase 1H NMR spectroscopy of its oxidative dication

Thamatam, Rajesh,Skraba, Sarah L.,Johnson, Richard P.

, p. 9122 - 9124 (2013)

Quaterrylene is prepared in a single reaction and high yield by Scholl-type coupling of perylene, utilizing trifluoromethanesulfonic acid as catalyst and DDQ or molecular oxygen as oxidant. Dissolution in 1 M triflic acid/dichloroethane with sonication yields the aromatic quaterrylene oxidative dication, which is characterized by its 1H NMR spectrum.
