Check Digit Verification of cas no

The CAS Registry Mumber 1440762-38-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,0,7,6 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1440762-38:
(9*1)+(8*4)+(7*4)+(6*0)+(5*7)+(4*6)+(3*2)+(2*3)+(1*8)=148
148 % 10 = 8
So 1440762-38-8 is a valid CAS Registry Number.

Synthesis of pyridine-fused perylene imides with an amidine moiety for hydrogen bonding

Ito, Satoru,Hiroto, Satoru,Shinokubo, Hiroshi

, p. 3110 - 3113 (2013/07/26)

Pyridine-fused perylene tetracarboxylic acid bisimides (PBIs) were synthesized via Suzuki-Miyaura coupling and acid condensation. The fused PBIs with electron-donating substituents exhibited an intramolecular charge transfer interaction. One of the N-alkyl substituents was selectively removed with BBr3 to create an amidine guest binding site. A hydrogen bonding interaction with pentafluorobenzoic acid changed the absorption spectra and enhanced fluorescence.
