Check Digit Verification of cas no

The CAS Registry Mumber 143064-49-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,0,6 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143064-49:
(8*1)+(7*4)+(6*3)+(5*0)+(4*6)+(3*4)+(2*4)+(1*9)=107
107 % 10 = 7
So 143064-49-7 is a valid CAS Registry Number.

Synthesis of acyltrifluoroborates

Dumas, Aaron M.,Bode, Jeffrey W.

supporting information; experimental part, p. 2138 - 2141 (2012/07/03)

Acylboranes are among the most elusive boron-containing organic functional groups, a fact that has impeded development of new reactions employing them as substrates. A new synthesis of acyltrifluoroborates from benzotriazole (Bt)-based N,O-acetals has bee

Addition of 1-(α-Alkoxybenzyl)benzotriazoles to Enol Ethers. New Routes to 1,3-Diethers

Katritzky, Alan R.,Rachwal, Stanislaw,Rachwal, Bogumila,Steel, Peter J.

, p. 4925 - 4931 (2007/10/02)

1-(α-Alkoxybenzyl)benzotriazoles undergo reversible ionization in solution to a benzotriazolyl anion (Bt-) and carboxonium cations PhCH:O+R.These cations can attack the β carbon of enol ethers to give cation adducts which add the Bt
