Check Digit Verification of cas no

The CAS Registry Mumber 57465-49-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,4,6 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 57465-49:
(7*5)+(6*7)+(5*4)+(4*6)+(3*5)+(2*4)+(1*9)=153
153 % 10 = 3
So 57465-49-3 is a valid CAS Registry Number.

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

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.
