Check Digit Verification of cas no

The CAS Registry Mumber 4023-86-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,2 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4023-86:
(6*4)+(5*0)+(4*2)+(3*3)+(2*8)+(1*6)=63
63 % 10 = 3
So 4023-86-3 is a valid CAS Registry Number.

Gold Catalysis of Non-Conjugated Haloacetylenes

Siera, Hannah,Semleit, Nina,Kreuzahler, Mathis,W?lper, Christoph,Haberhauer, Gebhard

, p. 1457 - 1470 (2020/12/09)

Gold-catalyzed reactions of conjugated haloacetylenes are well known and usually result in the formation of addition or dimerization products. Herein, we report a gold-catalyzed reaction of non-conjugated haloacetylenes, which leads exclusively to the hal

Catalytic regioselective synthesis of structurally diverse indene derivatives from N-benzylic sulfonamides and disubstituted alkynes

Liu, Cong-Rong,Yang, Fu-Lai,Jin, Yi-Zhou,Ma, Xian-Tao,Cheng, Dao-Juan,Li, Nan,Tian, Shi-Kai

supporting information; experimental part, p. 3832 - 3835 (2010/11/17)

An unprecedented protocol has been developed for the regioselective synthesis of structurally diverse indene derivatives from readily accessible N-benzylic sulfonamides and disubstituted alkynes through FeCl 3-catalyzed cleavage of sp3 carbon-nitrogen bonds to generate benzyl cation intermediates. In the presence of 10 mol % of FeCl 3, a broad range of N-benzylic sulfonamides smoothly react with internal alkynes, alkynylcarbonyl compounds, alkynyl chalcogenides, or alkynyl halides to afford various functionalized indene derivatives with extremely high regioselectivity.
