77764-68-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77764-68-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,7,6 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77764-68:
(7*7)+(6*7)+(5*7)+(4*6)+(3*4)+(2*6)+(1*8)=182
182 % 10 = 2
So 77764-68-2 is a valid CAS Registry Number.

Phthalimide-Carried Disulfur Transfer to Synthesize Unsymmetrical Disulfanes via Copper Catalysis

Zou, Jiaoxia,Chen, Jinhong,Shi, Tao,Hou, Yongsheng,Cao, Fei,Wang, Yongqiang,Wang, Xiaodong,Jia, Zhong,Zhao, Quanyi,Wang, Zhen

, p. 11426 - 11430 (2019/11/21)

A versatile Cu-catalyzed cross-coupling reaction to various unsymmetrical disulfanes has been presented, from phthalimide-carried disulfur transfer reagents and commercially available boronic acids under mild and practical conditions. The method features the unprecedented use of phthalimide-carried disulfurating reagents (Harpp reagent) in cross-coupling chemistry and is highlighted by the broad substrate scopes, even applicable for the transfer of aryl-disulfur moieties (ArSS-). Notably, the robustness of this methodology is shown by the late-stage modification of bioactive scaffolds of coumarin, estrone, and captopril.
