Check Digit Verification of cas no

The CAS Registry Mumber 109720-10-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,2 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 109720-10:
(8*1)+(7*0)+(6*9)+(5*7)+(4*2)+(3*0)+(2*1)+(1*0)=107
107 % 10 = 7
So 109720-10-7 is a valid CAS Registry Number.

Copper-mediated coupling of boronic acids, amines, and carbon disulfide: An approach to organic dithiocarbamates

Qi, Chaorong,Guo, Tianzuo,Xiong, Wenfang

, p. 2626 - 2630 (2016)

An efficient copper-mediated three-component coupling reaction of boronic acids, amines, and carbon disulfide has been developed, which provides a new approach to a wide range of functionalized dithiocarbamates in good to excellent yields. The present methodology has many advantages, such as mild reaction conditions, easily available substrates, wide substrate scope, and high functional-group tolerance.

Copper-Catalyzed Synthesis of S-Aryl Dithiocarbamates from Tetraalkylthiuram Disulfides and Aryl Iodides in Water

Wu, Xiang-Mei,Yan, Guo-Bing

supporting information, p. 610 - 614 (2019/03/08)

An efficient approach for the copper-catalyzed synthesis of aryl dithiocarbamates from aryl iodides and tetraalkylthiuram disulfides in water is described. Without additional ligand and organic solvent, the coupling reaction could provide a series of S-aryl dithiocarbamates in moderate to good yields.

A Highly Efficient CuCl 2 -Catalyzed C-S Coupling of Aryl Iodides with Tetraalkylthiuram Disulfides: Synthesis of Aryl Dithiocarbamates

Cao, Qiang,Peng, Han-Ying,Cheng, Yu,Dong, Zhi-Bing

, p. 1527 - 1534 (2018/01/17)

A highly efficient copper(II)-catalyzed C-S cross-coupling reaction of aryl iodides with tetraalkylthiuram disulfides was developed. With only 1 mol% of CuCl 2 as catalyst, zinc powder as reductant, and K 2 CO 3 as base, aryl iodides reacted with tetraalkylthiuram disulfides in DMSO furnishing the corresponding aryl dithiocarbamates in good to excellent yields. This protocol is an improvement of previous work, it features convenient performance, low addition of catalyst, no requirement for any ligand, and provides good yields. The method has a broad substrate scope and uses cheap and readily available starting materials.
