131665-81-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131665-81-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,6,6 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131665-81:
(8*1)+(7*3)+(6*1)+(5*6)+(4*6)+(3*5)+(2*8)+(1*1)=121
121 % 10 = 1
So 131665-81-1 is a valid CAS Registry Number.

Highly selective hydrosilylation of equilibrating allylic azides

Liu, Ruzhang,Liu, Yongmei,Wang, Juan,Wei, Zhen,Xue, Huaiguo

supporting information, p. 5038 - 5041 (2020/05/18)

The Pt-catalyzed hydrosilylation of equilibrating allylic azides is reported. The reaction provides only one out of four possible hydrosilylation products in good yields and with very high chemoselectivity (alk-1-enevs.alk-2-ene), regioselectivity (linearvs.branched), and excellent functional group tolerance.

Copper-catalyzed vinylsilane allylation

Cornelissen, Loic,Vercruysse, Sebastien,Sanhadji, Ayoub,Riant, Olivier

supporting information, p. 35 - 38 (2014/01/06)

Soft reaction conditions, particularly important in total synthesis, have dragged many researchers into the field of silylated organic compounds. Hereby, we describe a new copper-catalyzed vinylsilane transformation. Various vinylsilanes were allylated by using a copper(I) salt, and this led to the formation of polysubstituted 1,4-dienes bearing sensitive moieties such as halogens, ketones, and aldehydes. Hereby is described a new copper-catalyzed vinylsilane transformation. Various vinylsilanes were allylated by using copper(I) salts, and this led to the formation of polysubstituted 1,4-dienes bearing sensitive moieties such as halogens, ketones, and aldehydes.
