Check Digit Verification of cas no

The CAS Registry Mumber 91585-32-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,8 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91585-32:
(7*9)+(6*1)+(5*5)+(4*8)+(3*5)+(2*3)+(1*2)=149
149 % 10 = 9
So 91585-32-9 is a valid CAS Registry Number.

A Unified Approach for Divergent Synthesis of Heterocycles via TMSOTf-Catalyzed Formal [3+2] Cycloaddition of Electron-Rich Alkynes

Chen, Ping,Cao, Wei,Li, Xiangqian,Shi, Dayong

supporting information, p. 4789 - 4794 (2021/09/02)

We present a synthetic protocol for the construction of polysubstituted five-membered heterocycles via TMSOTf-catalyzed formal [3+2] cycloaddition of electron-rich alkynes, which features free from any metal, atom economy and water as the main by-product. Furthermore, alkenyl ether adduct has been verified as the key intermediate. Notably, by utilizing this approach, we can synthesize a broad range of polysubstituted furans, thiophenes and pyrroles, and extend this transformation to deliver fused-polyheterocycles. This reaction can be achieved on a gram scale and the corresponding products are intermediates for producing diverse potentially useful scaffolds. (Figure presented.).

Silver-catalyzed carbon-selenium cross-coupling using N-(phenylseleno)phthalimide: An alternate approach to the synthesis of organoselenides

Mukherjee, Nirmalya,Pal, Subhajit,Saha, Amit,Ranu, Brindaban C.

, p. 51 - 56 (2017/01/10)

Silver(I) catalyzed phenylselenylation of terminal alkynes and organoboronic acids has been demonstrated using N-(phenylseleno)phthalimide as an electrophilic SePh donor. A wide variety of terminal alkynes and organoboronic acids are selenylated efficiently to produce the corresponding alkynyl and diaryl selenides, respectively, in good yields. Silver(I) acts as a Lewis acid in this process.

Magnetite (Fe3O4) nanoparticles: An efficient and recoverable catalyst for the synthesis of alkynyl chalcogenides (selenides and tellurides) from terminal acetylenes and diorganyl dichalcogenides

Godoi, Marcelo,Liz, Daiane G.,Ricardo, Eduardo W.,Rocha, Manuela S.T.,Azeredo, Juliano B.,Braga, Antonio L.

, p. 3349 - 3354 (2014/05/06)

We present herein a new and efficient methodology for the synthesis of alkynyl chalcogenides from terminal acetylenes and diorganyl dichalcogenides, catalyzed by Fe3O4 nanoparticles. This new approach provided the desired products in good to excellent yields. Moreover, the catalyst was easily recoverable using an external magnet and reused for further experiments without loss of catalytic activity.
