Check Digit Verification of cas no
The CAS Registry Mumber 431039-10-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,1,0,3 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 431039-10:
(8*4)+(7*3)+(6*1)+(5*0)+(4*3)+(3*9)+(2*1)+(1*0)=100
100 % 10 = 0
So 431039-10-0 is a valid CAS Registry Number.

Isomer-Specific Hydrogen Bonding as a Design Principle for Bidirectionally Quantitative and Redshifted Hemithioindigo Photoswitches
Zweig, Joshua E.,Newhouse, Timothy R.
, p. 10956 - 10959 (2017)
A new class of bidirectionally quantitative photoswitches based on the hemithioindigo (HTI) scaffold is reported. Incorporation of a pyrrole hydrogen-bond donor leads to a bathochromic shift allowing for quantitative bidirectional isomerization. Additionally, extending conjugation from the electron-rich pyrrole results in quantitative visible-light photoswitches, as well as photoswitches that isomerize with red and near-infrared light. The presence of the hydrogen bond leading to the observed redshift is supported by computational and spectroscopic evidence.
