Check Digit Verification of cas no

The CAS Registry Mumber 1371607-83-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,1,6,0 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1371607-83:
(9*1)+(8*3)+(7*7)+(6*1)+(5*6)+(4*0)+(3*7)+(2*8)+(1*3)=158
158 % 10 = 8
So 1371607-83-8 is a valid CAS Registry Number.

Copper-Catalyzed 1,1-Alkylmonofluoroalkylation of Terminal Alkynes with Diazo Compounds and 2-Fluoro-1,3-dicarbonyl Compounds: Access toward (E)-β-Monofluoroalkyl-β,γ-unsaturated Esters or Ketones

Chen, Chen,Lv, Yunhe,Pu, Weiya,Wang, Shanshan,Zhu, Xueli

, p. 10043 - 10054 (2021/08/20)

An efficient copper-catalyzed three-component 1,1-alkylmonofluoroalkylation of terminal alkynes, diazo compounds, and 2-fluoro-1,3-dicarbonyl compounds for the synthesis of (E)-β-monofluoroalkyl-β,γ-unsaturated esters or ketones has been developed. The methodology features a broad substrate scope, an inexpensive and easily available catalytic system, and excellent selectivity with good yields. The mechanism of the tandem Cu-catalyzed cross-coupling and nucleophilic addition of allenes has been investigated.

Catalyst-free and highly selective electrophilic mono-fluorination of acetoacetamides: Facile and efficient preparation of 2-fluoroacetoacetamides in PEG-400

Bi, Jingjing,Zhang, Zhiguo,Liu, Qingfeng,Zhang, Guisheng

supporting information; experimental part, p. 1159 - 1162 (2012/06/18)

Series of α-mono-fluorinated acetoacetamides were synthesized under mild condition with industrialized Selectfluor as the F+ source in PEG-400. The approach avoided the use of base or metal catalyst, and most of cases proceeded in nearly quanti
