Check Digit Verification of cas no

The CAS Registry Mumber 1309650-22-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,6,5 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1309650-22:
(9*1)+(8*3)+(7*0)+(6*9)+(5*6)+(4*5)+(3*0)+(2*2)+(1*2)=143
143 % 10 = 3
So 1309650-22-3 is a valid CAS Registry Number.

Novel red-emitting thieno-[3,4-b]-pyrazine derivatives suitable for vacuum evaporation and solution method to fabricate non-doped OLEDs

Li, Qing,Li, Jiuyan,Yang, Ruixia,Deng, Lijun,Gao, Zhanxian,Liu, Di

experimental part, p. 674 - 680 (2012/02/06)

Two novel red-emitting thieno-[3,4-b]-pyrazine-cored molecules with phenyls (TP) or polyphenyls (Müllen type dendron, DTP) as peripheral groups were designed and synthesized. They have large Stokes shifts over 100 nm. DTP is thermally stable with decompos
