Check Digit Verification of cas no
The CAS Registry Mumber 424-16-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 424-16:
(5*4)+(4*2)+(3*4)+(2*1)+(1*6)=48
48 % 10 = 8
So 424-16-8 is a valid CAS Registry Number.

Facile syntheses of various per- or polyfluoroalkylated internal acetylene derivatives
Konno, Tsutomu,Chae, Jungha,Kanda, Masashi,Nagai, Go,Tamura, Kazushige,Ishihara, Takashi,Yamanaka, Hiroki

Treatment of per- or polyfluoroalkylated vinyl iodides 5 with 2equiv. of n-BuLi in THF produced the corresponding lithium acetylides in situ, which were transformed into zinc acetylides by the addition of ZnCl2· TMEDA complex into the reaction mixture. The in situ generated zinc acetylides were exposed to the cross-coupling conditions such as ArI/cat. Pd(PPh 3)4, reflux, 6-12 h, giving rise to the desired per- or polyfluoroalkylated acetylenes in high yields. In the case of trifluoromethylated acetylene, commercially available 2-bromo-3,3,3-trifluoropropene 6 could also be used instead of 5 as the starting material. In the acetylenes having a fluoroalkyl group and an aliphatic side chain, vinyl iodides 7, prepared by radical addition of perfluoroalkyl iodide to terminal acetylenes, were treated with t-BuOK at room temperature or at the reflux temperature of benzene, affording the desired compounds in good yields.
