64258-17-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 64258-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,2,5 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 64258-17:
(7*6)+(6*4)+(5*2)+(4*5)+(3*8)+(2*1)+(1*7)=129
129 % 10 = 9
So 64258-17-9 is a valid CAS Registry Number.

Cu-Catalyzed Electrophilic Disulfur Transfer: Synthesis of Unsymmetrical Disulfides

Wang, Weiguo,Lin, Yunzhi,Ma, Yudao,Tung, Chen-Ho,Xu, Zhenghu

, p. 3829 - 3832 (2018)

An efficient electrophilic persulfuration reaction leading to unsymmetrical disulfides and polysulfides has been developed. Various nucleophiles, including aryl boronic acids, β-keto esters, and thiols, can be used as substrates. The notable features of t

Visible-light photocatalytic selective aerobic oxidation of thiols to disulfides on anatase TiO2

Xu, Hui,Shi, Ji-Long,Lyu, Shaoshuai,Lang, Xianjun

, p. 1468 - 1473 (2020/04/29)

This work presents the visible-light photocatalytic selective oxidation of thiols to disulfides with molecular oxygen (O2) on anatase TiO2. The high specific surface area of anatase TiO2 proved to be especially critical in

T BuOK-triggered bond formation reactions

Xu, Yulong,Shi, Xiaonan,Wu, Lipeng

, p. 24025 - 24029 (2019/08/13)

Recently, inexpensive and readily available tBuOK has seen widespread use in transition-metal-free reactions. Herein, we report the use of tBuOK for S-S, S-Se, NN and CN bond formations, which significantly extends the scope of tBuOK in chemical synthesis. Compared with traditional methods, we have realized mild and general methods for disulfide, azobenzenes imine etc. synthesis.
