68971-91-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 68971-91-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,9,7 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 68971-91:
(7*6)+(6*8)+(5*9)+(4*7)+(3*1)+(2*9)+(1*1)=185
185 % 10 = 5
So 68971-91-5 is a valid CAS Registry Number.

Illuminating Stannylation

Sakamoto, Kyoka,Nagashima, Yuki,Wang, Chao,Miyamoto, Kazunori,Tanaka, Ken,Uchiyama, Masanobu

supporting information, p. 5629 - 5635 (2021/05/04)

We have developed photoboosted stannylation reactions of terminal alkynes (linear-selective hydrostannylation) and fluoroarenes (defluorostannylation), in which the stannyl anion is photoexcited to an excited triplet (T1) stannyl diradical species. This u

Stannyl-Lithium: A Facile and Efficient Synthesis Facilitating Further Applications

Wang, Dong-Yu,Wang, Chao,Uchiyama, Masanobu

supporting information, p. 10488 - 10491 (2015/09/28)

We have developed a highly efficient, practical, polycyclic aromatic hydrocarbon (PAH)-catalyzed synthesis of stannyl lithium (Sn-Li), in which the tin resource (stannyl chloride or distannyl) is rapidly and quantitatively transformed into Sn-Li reagent at room temperature without formation of any (toxic) byproducts. The resulting Sn-Li reagent can be stored at ambient temperature for months and shows high reactivity toward various substrates, with quantitative atom efficiency.
