3944-07-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3944-07-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,4 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3944-07:
(6*3)+(5*9)+(4*4)+(3*4)+(2*0)+(1*7)=98
98 % 10 = 8
So 3944-07-8 is a valid CAS Registry Number.

Rhodium-Catalyzed Reaction of Silacyclobutanes with Unactivated Alkynes to Afford Silacyclohexenes

Chen, Hua,Chen, Yi,Tang, Xiaoxiao,Liu, Shunfa,Wang, Runping,Hu, Tianbao,Gao, Lu,Song, Zhenlei

supporting information, p. 4695 - 4699 (2019/03/07)

A Rh-catalyzed reaction of silacyclobutanes (SCBs) with unactivated alkynes has been developed to form silacyclohexenes with high chemoselectivity. Good enantioselectivity at the stereogenic silicon center was achieved using a chiral phosphoramidite ligand. The resulting silacyclohexenes are useful scaffolds for synthesizing structurally attractive silacyclic compounds.
