Check Digit Verification of cas no
The CAS Registry Mumber 1047660-72-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,7,6,6 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1047660-72:
(9*1)+(8*0)+(7*4)+(6*7)+(5*6)+(4*6)+(3*0)+(2*7)+(1*2)=149
149 % 10 = 9
So 1047660-72-9 is a valid CAS Registry Number.

Ru-Catalyzed Geminal Hydroboration of Silyl Alkynes via a New gem-Addition Mechanism
Feng, Qiang,Wu, Haonan,Li, Xin,Song, Lijuan,Chung, Lung Wa,Wu, Yun-Dong,Sun, Jianwei

While 1,2-addition represents the most common mode of alkyne hydroboration, herein we describe a new 1,1-hydroboration mode. It is the first demonstration of gem-(H,B) addition to an alkyne triple bond. With the superior [CpRu(MeCN)3]PF6 catalyst, a range of silyl alkynes reacted efficiently with HBpin under mild conditions to form various synthetically useful silyl vinyl boronates with complete stereoselectivity and broad functional group compatibility. An extension to germanyl alkynes and the hydrosilylation of alkynyl boronates toward the same type of products were also achieved. Mechanistically, this process features a new pathway featuring gem-(H,B) addition to form the key α-boryl-α-silyl Ru-carbene intermediate followed by silyl migration. It is believed that the orbital interaction between boron and Cβ in the coplanar relationship between the boron atom and the ruthenacyclopropene ring preceding boron migration is responsible for the new reactivity. Control experiments and DFT (including molecular dynamics) calculations provided important insights into the mechanism, which excluded the involvement of a metal vinylidene intermediate. This study represents a new step forward not only for alkyne hydroboration but also for other geminal additions of alkynes.
