Check Digit Verification of cas no

The CAS Registry Mumber 1256705-52-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,7,0 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1256705-52:
(9*1)+(8*2)+(7*5)+(6*6)+(5*7)+(4*0)+(3*5)+(2*5)+(1*2)=158
158 % 10 = 8
So 1256705-52-8 is a valid CAS Registry Number.

Near-infrared nitrofluorene substitued aza-Boron-dipyrromethenes dyes

Bellier, Quentin,Pegaz, Sarah,Aronica, Christophe,Guennic, Boris Le,Andraud, Chantal,Maury, Olivier

supporting information; experimental part, p. 22 - 25 (2011/03/22)

The synthesis, spectroscopic properties, and TD-DFT calculations of new aza-Boron-dipyromethene dyes featuring pendant nitrofluorenylethynyl substituents are described. This functionalization allows for moving the luminescence in the NIR, conserving a good quantum yield efficiency.

Highly near-infrared photoluminescence from aza-borondipyrromethene-based conjugated polymers

Yoshii, Ryousuke,Nagai, Atsushi,Chujo, Yoshiki

experimental part, p. 5348 - 5356 (2011/06/22)

Near-infrared (NIR) emissive conjugated polymers were prepared by palladium-catalyzed Sonogashira polymerization of diiodobenzene-functionalized aza-borondipyrromethene (Aza-BODIPY) monomers, which were substituted at 3 and 5 or 1 and 7 positions on the A
