Check Digit Verification of cas no

The CAS Registry Mumber 1257331-74-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,3,3 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1257331-74:
(9*1)+(8*2)+(7*5)+(6*7)+(5*3)+(4*3)+(3*1)+(2*7)+(1*4)=150
150 % 10 = 0
So 1257331-74-0 is a valid CAS Registry Number.

Tuning the singlet-triplet gap in metal-free phosphorescent π-conjugated polymers

Chaudhuri, Debangshu,Wettach, Henning,Van Schooten, Kipp J.,Liu, Su,Sigmund, Eva,Hoeger, Sigurd,Lupton, John M.

supporting information; experimental part, p. 7714 - 7717 (2010/12/25)

Glow in the dark: A tunable singlet-triplet exchange gap arises in optically active conjugated polymers that exhibit both strong fluorescence from the singlet state and pronounced phosphorescence from triplet excitations (see picture). The polymers were incorporated into organic light-emitting diodes (OLEDs).
