Check Digit Verification of cas no

The CAS Registry Mumber 1174638-53-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,4,6,3 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1174638-53:
(9*1)+(8*1)+(7*7)+(6*4)+(5*6)+(4*3)+(3*8)+(2*5)+(1*3)=169
169 % 10 = 9
So 1174638-53-9 is a valid CAS Registry Number.

Chemo- and stereoselective synthesis of fluorinated enamides from ynamides in HF/pyridine: Second-generation approach to potent ureas bioisosteres

Métayer, Beno?t,Compain, Guillaume,Jouvin, Kévin,Martin-Mingot, Agnès,Bachmann, Christian,Marrot, Jér?me,Evano, Gwilherm,Thibaudeau, Sébastien

, p. 3397 - 3410 (2015/04/22)

(E)- and (Z)-α-fluoroenamides could be easily prepared with high levels of chemo- and regioselectivities by hydrofluorination of readily available ynamides with HF/pyridine. The scope and limitations of this new process for the hydrofluorination of ynamides, as well as the stability of the resulting α-fluoroenamides, have been extensively studied. Theoretical calculations at the MP2 and B3LYP levels of theory showed that the resulting fluoroenamides exhibit geometrical and electronic properties that partially mirror those of ureas, therefore demonstrating that the hydrofluorination of ynamides provides a general, straightforward, and user-friendly approach to bioisosteres of ureas, potent building blocks for biological studies and medicinal chemistry.

Copper-mediated selective cross-coupling of 1,1-dibromo-1-alkenes and heteronucleophiles: Development of general routes to heterosubstituted alkynes and alkenes

Jouvin, Kevin,Coste, Alexis,Bayle, Alexandre,Legrand, Frederic,Karthikeyan, Ganesan,Tadiparthi, Krishnaji,Evano, Gwilherm

, p. 7933 - 7947 (2013/01/16)

Efficient and general procedures for the cross-coupling of 1,1-dibromoalkenes and N-, O-, and P-nucleophiles are reported. Fine-tuning of the reaction conditions allows for either site-selective, double, or alkynylative cross-coupling, therefore providing
