Check Digit Verification of cas no

The CAS Registry Mumber 69036-39-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,0,3 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 69036-39:
(7*6)+(6*9)+(5*0)+(4*3)+(3*6)+(2*3)+(1*9)=141
141 % 10 = 1
So 69036-39-1 is a valid CAS Registry Number.

A new oxapalladacycle generated via ortho C-H activation of phenylphosphinic acid: An efficient catalyst for Markovnikov-type additions of E-H bonds to alkynes

Xu, Qing,Shen, Ruwei,Ono, Yutaka,Nagahata, Ritsuko,Shimada, Shigeru,Goto, Midori,Han, Li-Biao

supporting information; scheme or table, p. 2333 - 2335 (2011/04/15)

A new oxapalladacycle 3 can be conveniently prepared via direct ortho palladation of diphenylphosphinic acid with palladium acetate. Catalysts derived from 3 can efficiently catalyze Markovnikov-type additions of E-H bonds (P(O)-H, S-H and spC-H) to alkyn

Stereo-recognizing transformation of (E)-alkenyl halides into sulfides catalyzed by nickel(0) triethyl phosphite complex

Yatsumonji, Yasutaka,Okada, Orie,Tsubouchi, Akira,Takeda, Takeshi

, p. 9981 - 9987 (2007/10/03)

(E)-Alkenyl halides were transformed into (E)-alkenyl sulfides by the nickel(0) triethyl phosphite complex-catalyzed reaction with thiols, whereas (Z)-alkenyl halides gave alkynes under the same reaction conditions. Aryl halides were also transformed into aryl sulfides using the same reagent system.

Rhodium-catalyzed highly selective thioformylation of acetylenes with thiols and carbon monoxide

Kawakami, Jun-Ichi,Takeba, Mitsuhiro,Kamiya, Ikuyo,Sonoda, Noboru,Ogawa, Akiya

, p. 6559 - 6567 (2007/10/03)

Highly regioselective thioformylation of terminal acetylenes with thiols and carbon monoxide has been developed by the use of rhodium(I) complexes as the catalyst: formyl and thio groups are introduced into the terminal and inner positions of acetylenes, respectively. The thioformylation is performed in the presence of a catalytic amount of rhodium(I) complexes, such as RhH(CO)(PPh3)3, RhCl(PPh3)3, and RhCl(CO)(PPh3)2, under the pressure of CO (3 MPa) at 120°C in CH3CN to provide β-thio-α,β-unsaturated aldehydes in good yields. This thioformylation can be applied to a variety of terminal acetylenes and aromatic thiols. A mechanistic proposal includes the formation of the rhodium sulfide complex as the key species.
