193980-17-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 193980-17-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,9,8 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 193980-17:
(8*1)+(7*9)+(6*3)+(5*9)+(4*8)+(3*0)+(2*1)+(1*7)=175
175 % 10 = 5
So 193980-17-5 is a valid CAS Registry Number.

Push-pull type of diphenoquinoid chromophores as novel near-infrared dyes
Inoue, Shinobu,Aso, Yoshio,Otsubo, Tetsuo
, p. 1105 - 1106 (2007/10/03)
Novel push-pull diphenoquinoid chromophores, in which one of the terminal positions carries a strong donor group, benzo-1,3-dithiol-2-ylidene, and the other a strong acceptor group, dicyanomethylene, are synthesized and show a strong absorption in the nea
