Check Digit Verification of cas no

The CAS Registry Mumber 1221408-65-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,4,0 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1221408-65:
(9*1)+(8*2)+(7*2)+(6*1)+(5*4)+(4*0)+(3*8)+(2*6)+(1*5)=106
106 % 10 = 6
So 1221408-65-6 is a valid CAS Registry Number.

Discovery of naphthalimide conjugates as fluorescent probes for α1-adrenoceptors

Zhang, Wei,Zhou, Xin-Yang,Yu, Qin-Ying,Du, Lu-Pei,Li, Min-Yong

, p. 185 - 189 (2016)

α1-Adrenoceptors (α1-ARs), including at least three subtypes, α1A, α1B and α1D, which play essential roles in G protein-coupled receptors (GPCRs), can convey multiple pivotal extracellular signals in varied tissues and organs. In this research, a series of napthalimide-based small-molecule fluorescent probes (1a–1f) for α1-ARs, including two parts, a pharmacophore (quinazoline and phenylpiperazine) for α1-AR recognition and a fluorophore (naphthalimide) for visualization, were designed and synthesized successfully. These compounds display excellent fluorescence property and high affinity to receptors, which were used successfully for in vitro visualization of α1-adrenoceptors.
