Check Digit Verification of cas no

The CAS Registry Mumber 1621183-40-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,1,1,8 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1621183-40:
(9*1)+(8*6)+(7*2)+(6*1)+(5*1)+(4*8)+(3*3)+(2*4)+(1*0)=131
131 % 10 = 1
So 1621183-40-1 is a valid CAS Registry Number.

A novel low-bandgap conjugated polymer based on Ru(II) bis(acetylide) complex and BODIPY moieties

Zhang, Shuwei,Sheng, Yuan,Wei, Guo,Quan, Yiwu,Cheng, Yixiang,Zhu, Chengjian

, p. 1686 - 1692 (2014/05/20)

A novel conjugated polymer P-1 incorporating Ru(II) bis(acetylide) complex and borondipyrromethene (BODIPY) moieties in the main chain was synthesized by Pd-catalyzed Sonogashira coupling reaction of diethynyl substituted BODIPY derivative (M-1) and Ru(II) bis(acetylide) complex (M-2), and the reference polymer P-2 was obtained from the same method as preparation of P-1. Compared with P-2, Ru(II)-containing polymer P-1 shows low-bandgap as 0.87 eV from cyclic voltammetry, and obvious redshifts in both UV-vis absorption and fluorescence spectra.
