Check Digit Verification of cas no

The CAS Registry Mumber 1286729-19-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,6,7,2 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1286729-19:
(9*1)+(8*2)+(7*8)+(6*6)+(5*7)+(4*2)+(3*9)+(2*1)+(1*9)=198
198 % 10 = 8
So 1286729-19-8 is a valid CAS Registry Number.

An eco-sustainable erbium(III) triflate catalyzed formation and cleavage of tert -butyl ethers

Procopio, Antonio,Costanzo, Paola,Curini, Massimo,Nardi, Monica,Oliverio, Manuela,Paonessa, Rosina

supporting information; experimental part, p. 73 - 78 (2011/03/19)

An eco-compatible method, which permits the formation or cleavage of tert-butyl ethers of alcohols and phenols, is proposed. The protection step is performed in solvent-free conditions at room temperature using catalytic amount of Er(OTf)3. The catalyst is easily- recovered from the aqueous phase and reused several times without significant loss of activity. The deprotection step developed is also highly eco-friendly since the tert-butyl group is removed very quickly from alcohols and phenols in methanol using MW irradiation-.
