Check Digit Verification of cas no

The CAS Registry Mumber 58634-67-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,6,3 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 58634-67:
(7*5)+(6*8)+(5*6)+(4*3)+(3*4)+(2*6)+(1*7)=156
156 % 10 = 6
So 58634-67-6 is a valid CAS Registry Number.

Rhodium(iii)-catalyzed directed amidation of unactivated C(sp3)-H bonds to afford 1,2-amino alcohol derivatives

Dong, Yi,Chen, Jiajing,Xu, Heng

supporting information, p. 11096 - 11099 (2018/11/21)

A rhodium-catalyzed directed C(sp3)-H amidation to afford 1,2-amino alcohol oxime derivatives has been developed with good yields and a broad substrate scope. In previous methods for this type of reaction, 1-arylethan-1-ol oxime analogues were

Transformation of masked benzyl alcohols to: O -aminobenzaldehydes through C-H activation: A facile approach to quinazolines

Chen, Xiaolan,Han, Jian,Zhu, Yan,Yuan, Chunchen,Zhang, Jingyu,Zhao, Yingsheng

supporting information, p. 10241 - 10244 (2016/10/22)

Direct transformation of a directing group to important synthetic units would provide a high atom efficiency synthetic approach in synthetic chemistry. Herein, a convenient protocol for the synthesis of o-aminobenzaldehyde and benzoxazole derivatives from benzyl alcohols has been developed by employing (N,N-dimethyl)oxamoyl amide as a directing group in a palladium-catalyzed intramolecular amination. Furthermore, the attached directing center may not only be transformed into the product, but may also be further applied to generate synthetically important quinazoline and quinoline units. Finally, a high atom efficiency one-pot, two-step approach to form quinazolines from benzyl alcohol derivatives has been achieved in good yields, thus demonstrating its high utility.

NBu4NI-catalyzed intermolecular C-O cross-coupling reactions: Synthesis of alkyloxyamines

Lv, Yunhe,Sun, Kai,Wang, Tingting,Li, Gang,Pu, Weiya,Chai, Nannan,Shen, Huihui,Wu, Yingtao

, p. 72142 - 72145 (2015/09/08)

A practical and simple nBu4NI-catalyzed C-O bond formation for the synthesis of alkyloxyamines was achieved under metal-free conditions. The reaction is applicable to the coupling of a range of benzylic and allylic hydrocarbons with N-hydroxyphthalimide and is tolerant of various functional groups. The reaction mechanism was primarily investigated and a radical process was proposed.

Cu-facilitated C-O bond formation using N-hydroxyphthalimide: Efficient and selective functionalization of benzyl and allylic C-H bonds

Ji, Min Lee,Eun, Ju Park,Seung, Hwan Cho,Chang, Sukbok

supporting information; experimental part, p. 7824 - 7825 (2009/02/01)

A highly efficient protocol for the benzyl or allylic C-H functionalization of simple hydrocarbons has been developed using stoichiometric amounts of N-hydroxyphthalimide and PhI(OAc)2 in the presence of CuCl catalyst. The reaction was revealed to proceed via a radical pathway, in which phthalimide N-oxyl (PINO) radical plays a dual role, serving as a catalytic hydrogen abstractor from hydrocarbons as well as a stoichiometric reagent to couple with the resultant alkyl radicals.
