Check Digit Verification of cas no
The CAS Registry Mumber 4122-57-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,2 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4122-57:
(6*4)+(5*1)+(4*2)+(3*2)+(2*5)+(1*7)=60
60 % 10 = 0
So 4122-57-0 is a valid CAS Registry Number.

Bismuth(III) triflate: A safe and easily handled precursor for triflic acid: Application to the esterification reaction
Kwie, Franciane Ho A.,Baudoin-Dehoux, Cecile,Blonski, Casimir,Lherbet, Christian
experimental part, p. 1082 - 1087 (2010/05/01)
A series of carboxylic acids were converted into their corresponding methyl esters using bismuth(III) triflate as a catalyst in methanol. Good to excellent yields were obtained for different aliphatic or aromatic starting materials. In the reaction, bismuth triflate acts as a precursor that, upon hydrolysis, liberates sufficient triflic acid to catalyze the esterification.
Synthons for biologically active compounds on the basis of naphthalene ozonolysis products

Ozonolysis of naphthalene in aqueous methanol, followed by the reduction of peroxy compounds thus formed with potassium iodide in the presence of acetic acid, gave 3-methoxy-2-benzofuran-1(3H)-one. In the absence of water, the product was methyl o-formylbenzoate. The latter was used as a synthon for the preparation of aromatic analogs of (2E)-2,6-dimethyloct-2-ene-1,8-diol ethers which are effective juvenoids. Pleiades Publishing, Inc., 2006.
