Check Digit Verification of cas no

The CAS Registry Mumber 81051-12-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,5 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81051-12:
(7*8)+(6*1)+(5*0)+(4*5)+(3*1)+(2*1)+(1*2)=89
89 % 10 = 9
So 81051-12-9 is a valid CAS Registry Number.

Substituent Effect Induces Emission Modulation of Stilbene Photoswitches by Spatial Tuning of the N/B Electronic Constraints

Chen, Pangkuan,Ji, Guangqian,Wang, Nan,Yin, Xiaodong

supporting information, (2020/07/30)

We present a family of stilbene derivatives (1-4) ortho-functionalized with an electron donor and acceptor. Their emission was tuned by donor substitutions, dictating charge transfer dependent on the N···B spatial separation. The steric reduction of subst
