Check Digit Verification of cas no

The CAS Registry Mumber 199786-58-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,7,8 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 199786-58:
(8*1)+(7*9)+(6*9)+(5*7)+(4*8)+(3*6)+(2*5)+(1*8)=228
228 % 10 = 8
So 199786-58-8 is a valid CAS Registry Number.

A novel class of phenylene-(poly)ethynylene-based dye Sensor 1 with remarkable properties of solvatochromism has been designed and synthesized. A long, coplanar and asymmetry electron-rich π-conjugated structure endows Sensor 1 with maximum solvatochromic

Pd(II)-Catalyzed Synthesis of Benzocyclobutenes by β-Methylene-Selective C(sp3)-H Arylation with a Transient Directing Group

Chen, Xiangyang,Hoskin, John F.,Houk, K. N.,Provencher, Philip A.,Sorensen, Erik J.,Wong, Jonathan J.,Yu, Jin-Quan

supporting information, p. 20035 - 20041 (2021/12/09)

Methylene-selective C-H functionalization is a significant hurdle that remains to be addressed in the field of Pd(II) catalysis. We report a Pd(II)-catalyzed synthesis of benzocyclobutenes by methylene-selective C(sp3)-H arylation of ketones. The reaction utilizes glycine as a transient directing group and a 2-pyridone ligand, which may govern the methylene selectivity by making intimate molecular associations with the substrate during concerted metalation-deprotonation. This reaction is shown to be highly selective for intramolecular methylene C(sp3)-H arylation, thus enabling sequential C(sp3)-H functionalization.

CuSO4-Catalyzed dual annulation to synthesize O, S or N-containing tetracyclic heteroacenes

Kang, Yan-Biao,Qu, Jian-Ping,Shan, Xiang-Huan,Yang, Bo

supporting information, p. 4063 - 4066 (2020/04/20)

In this work, CuSO4 is utilized as a practical redox catalyst for tandem dual annulation in the synthesis of indole-fused tetracyclic heteroacenes, which are important skeletons in both medicinal chemistry and materials chemistry. The preparation of such skeletons in a convenient and efficient manner is in high demand. This method realizes the modular synthesis of benzofuro-, benzothieno-, and indoloindoles from abundant feedstocks such as 2-halobenzyl halides and nitrile derivatives in up to 99% yields, providing a rapid access to diverse indole-fused heteroacenes with biological or optoelectronic properties.
