Check Digit Verification of cas no

The CAS Registry Mumber 1403775-52-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,3,7,7 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1403775-52:
(9*1)+(8*4)+(7*0)+(6*3)+(5*7)+(4*7)+(3*5)+(2*5)+(1*2)=149
149 % 10 = 9
So 1403775-52-9 is a valid CAS Registry Number.

Gas-Chromatographic identifi cation of products formed in iodination of methyl phenols by retention indices

Gruzdev,Kuzivanov,Zenkevich,Kondratenok

, p. 1355 - 1365 (2013/01/15)

Iodination reaction followed by conversion of iodine-substituted methylphenols to the corresponding trifl uoroacetates was suggested for improving the sensitivity of the gas-chromatographic determination of phenol and its methyl-substituted derivatives (al isomers of mono- and diethylphenols, 2,3,5-, 2,3,6-, and 3,4,5-trimethylphenols) in aqueous media. Acylation products of iodo methylphenols (104 compounds) were identifi ed by linear-logarithmic retention indices on a standard nonpolar polydimethylsiloxane stationary phase, and the pattern of their variation with the number and nature of substituents were characterized. A procedure for identifi cation of methyl-substituted phenols in water in their gas-chromatographic determination with an electron-capture detector was developed. Pleiades Publishing, Ltd., 2012.
