Check Digit Verification of cas no

The CAS Registry Mumber 1293991-08-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,3,9,9 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1293991-08:
(9*1)+(8*2)+(7*9)+(6*3)+(5*9)+(4*9)+(3*1)+(2*0)+(1*8)=198
198 % 10 = 8
So 1293991-08-8 is a valid CAS Registry Number.

Enol silyl ethers via copper(II)-catalyzed C-O bond formation

Chan, Daniel G.,Winternheimer, David J.,Merlic, Craig A.

supporting information; experimental part, p. 2778 - 2781 (2011/08/02)

Copper(II) acetate catalyzes the coupling of pinacol vinylboronates with silanols producing enol silyl ethers. This represents a novel enol silyl ether synthesis via formation of the C-O bond instead of the conventional Si-O bond. This also constitutes the first transition-metal-catalyzed oxidative cross-coupling with silanols.
