222844-98-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 222844-98-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,8,4 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 222844-98:
(8*2)+(7*2)+(6*2)+(5*8)+(4*4)+(3*4)+(2*9)+(1*8)=136
136 % 10 = 6
So 222844-98-6 is a valid CAS Registry Number.

P-Methoxybenzyl-N-phenyl-2,2,2-trifluoroacetimidate: A versatile reagent for mild acid catalyzed etherification

Barroca-Aubry, Nadine,Benchekroun, Mohamed,Gomes, Filipe,Bonnaffé, David

, p. 5118 - 5121 (2013/09/02)

PMB-NPTFA 1a is a new month bench stable and powerful reagent for the formation of PMB ethers. Several alcohols were protected in high yields and short reaction times, using low reagent loading and small catalytic amounts of Bi(OTf)3. The mild

Regioselective deprotection of p-methoxybenzyl ethers of furanose derivatives

Bouzide, Abderrahim,Sauve, Gilles

, p. 2883 - 2886 (2007/10/03)

Reaction of per-p-methoxybenzylated hexofuranoses and pentofuranoses with either a catalytic amount of tin chloride dihydrate (SnCl2·2H2O) or 0.5-10% solution of trifluoroaoetic acid in dichloromethane afforded regioselectively the corresponding monosaccharide derivatives having a single free hydroxyl group at C(5) in good yields.
