Check Digit Verification of cas no

The CAS Registry Mumber 111789-39-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,7,8 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 111789-39:
(8*1)+(7*1)+(6*1)+(5*7)+(4*8)+(3*9)+(2*3)+(1*9)=130
130 % 10 = 0
So 111789-39-0 is a valid CAS Registry Number.

Palladium porphyrin catalyzed hydrogenation of alkynes: Stereoselective synthesis of cis -alkenes

Nishibayashi, Ryo,Kurahashi, Takuya,Matsubara, Seijiro

supporting information, p. 1287 - 1290 (2014/06/10)

(Tetraphenylporphyrin)palladium was developed as a catalyst for the chemoselective and stereoselective hydrogenation of alkynes to cis-alkenes by the syn-addition of hydrogen. Alkynes containing various functional groups were tolerated in the reaction, which gave the corresponding cis-alkenes in good to excellent yields. Georg Thieme Verlag Stuttgart New York.

Syntheses of Monounsaturated Sex Pheromones of Lepidoptera via 3-Alkyn-1-ols

Pop, Lidia,Oprean, I.,Barabas, A.,Hodosan, F.

, p. 867 - 878 (2007/10/02)

3-Alkyn-1-ols as intermediate synthons in the preparation of some Lepidoteran sex pheromones were utilized.Characteristic fragmentations reflecting the position of the triple bond were found in the mass spectra of 3-alkyn-1-ols and alkyn-1-yl acetates in contrast to 1-tert-butoxy-alkynes.A partial isomerization of 1-tosyloxy-3-(Z)-octene to 1-bromo-3-(E)-octene within the reaction with NaBr in DMF was noticed by GC and 13C-n.m.r., for which a mechanism involving homoconjugation in an intermediate non-classical carbonium ion was suggested.
