Check Digit Verification of cas no

The CAS Registry Mumber 25090-28-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,0,9 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 25090-28:
(7*2)+(6*5)+(5*0)+(4*9)+(3*0)+(2*2)+(1*8)=92
92 % 10 = 2
So 25090-28-2 is a valid CAS Registry Number.

An Empirical Aromativcity Index (AIRT) Based on "Reversion to Type" in the Hydrolysis of Methyl Ethers, Methyl Thioethers, and Methyl Selenoethers Derived from Some Heterocyclic and Homocyclic Polyenes

Capon, Brian,Lew, Sing Quan

, p. 7823 - 7838 (1992)

Hydronium ion catalysed hydrolysis and deuterium exchange in CD3CN-D2O (9:1 v/v) of the following compounds have been investigated: 1-methoxy-, 3-methoxy- and 1-methylthio-cyclohepta-1,3,5-triene, 1-methoxy-cyclooctatetraene, 2-methylthio-, 3-methylthio- and 2-methylseleno-benzofuran, 2-methylthio- and 3-methylthio-benzothiophene, and 2-methylthio-N-methyl-indole.The values of log kex/khyd for these compounds and those of a previous investigation have been used to define an aromaticity scale based on "reversion to type".
