Check Digit Verification of cas no

The CAS Registry Mumber 34328-31-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,3,2 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 34328-31:
(7*3)+(6*4)+(5*3)+(4*2)+(3*8)+(2*3)+(1*1)=99
99 % 10 = 9
So 34328-31-9 is a valid CAS Registry Number.

Binuclear Palladium Complex Immobilized on Mesoporous SBA-16: Efficient Heterogeneous Catalyst for the Carbonylative Suzuki Coupling Reaction of Aryl Iodides and Arylboronic Acids Using Cr(CO)6 as Carbonyl Source

Niakan, Mahsa,Asadi, Zahra,Emami, Mohammad

, p. 404 - 418 (2020/01/03)

Abstract: In this study, a binuclear palladium complex immobilized on the organo-functionalized SBA-16 was prepared and structurally characterized by routine techniques. Characterizations indicated that the mesostructure of SBA-16 was maintained after the immobilization of palladium complex. Then, the prepared nanomaterial was applied as a heterogeneous catalyst in the carbonylative Suzuki coupling reaction of aryl iodides with arylboronic acids using Cr(CO)6 as carbonyl source. The catalyst was efficiently promoted the coupling reactions of various aryl iodides and arylboronic acids to give the corresponding diaryl ketones in excellent yields. Moreover, the catalyst was readily recovered by filtration and could be reused for seven cycles without losing its structural integrity and catalytic activity.

Schirmer, Tobias Emanuel,Wimmer, Alexander,Weinzierl, Florian Wolfgang Clemens,K?nig, Burkhard

supporting information, p. 10796 - 10799 (2019/09/13)

The dual catalytic arylation of aromatic aldehydes by aryl bromides using UV-irradiation and a nickel catalyst is reported. The reaction product serves as a photocatalyst and a hydrogen atom transfer agent for this transformation.

Base free Suzuki acylation reactions of sodium (aryl trihydroxyborate) salts: A novel synthesis of substituted aryl ketones

Sithebe, Siphamandla,Molefe, Patience

, p. 305 - 311 (2017/07/13)

The first simple and efficient base free Pd(PPh3)4 catalysed synthesis of substituted aryl ketones from acyl chlorides and easily accessible sodium aryl trihydroxyborate salts in aqueous toluene is reported. The reaction conditions appeared versatile and tolerable to a variety of functional groups including, CF3, OMe, SMe, Br, NO2, F, OH and NH2 furnishing 25 examples of substituted aryl ketones in isolated yields of up to 96% in 24 h. Beside the high purity, the ease and convenience of the isolation compared to boronic acids, sodium aryl trihydroxyborate salts could be used subsequently without the addition of excess amount of an activator and are more user-friendly in terms of the use of accurate reaction stoichiometry.
