Check Digit Verification of cas no

The CAS Registry Mumber 1281983-33-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,1,9,8 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1281983-33:
(9*1)+(8*2)+(7*8)+(6*1)+(5*9)+(4*8)+(3*3)+(2*3)+(1*3)=182
182 % 10 = 2
So 1281983-33-2 is a valid CAS Registry Number.

Strategic construction of ethene-bridged BODIPY arrays with absorption bands reaching the near-infrared II region

Gong, Qingbao,Guo, Xing,Hao, Erhong,Jiao, Lijuan,Kang, Zhengxin,Wang, Dandan,Wang, Hua,Wu, Qinghua

, p. 7513 - 7517 (2020)

An efficient strategy for the controllable synthesis of BODIPY arrays based on the Stille cross-coupling reaction has been developed, from which a family of well-defined ethenebridged BODIPY arrays from dimer to hexamer was synthesized. These arrays showed strong absorptions reaching the near-infrared II (NIR II, 1000-1700 nm) region with maxima tunable from 702 nm (dimer) to 1114 nm (hexamer) and possessed efficient lightharvesting capabilities, excellent photostability, and good photothermal conversion abilities under NIR light irradiation.

Metal-mediated synthesis of antiaromatic porphyrinoids from a BODIPY precursor

Sakida, Takafumi,Yamaguchi, Shigeru,Shinokubo, Hiroshi

, p. 2280 - 2283 (2011/04/21)

(Figure Presented) Metallic route to antiaromaticity: The synthesis of a butadiyne-bridged cyclic BODIPY dimer (see structure; C white, B orange, N blue, F green) and trimer was achieved through Pd-catalyzed Stille coupling and Cu-mediated Glaser-type coupling. These cyclic BODIPYs were found to be stable 24π- and 36π-antiaromatic porphyrinoids with planar conformations, and their structures, electronic states, and reactivity were explored.
