Check Digit Verification of cas no

The CAS Registry Mumber 20049-05-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,0,4 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20049-05:
(7*2)+(6*0)+(5*0)+(4*4)+(3*9)+(2*0)+(1*5)=62
62 % 10 = 2
So 20049-05-2 is a valid CAS Registry Number.

THE ROLE OF THE 1,2-HYDRIDE SHIFT IN THE ISOMERIZATION PROCESSES OF CYCLOALKYL CARBOCATIONS

Voronenkov, V. V.,Dzyuba, I. B.,Kryukov, S. I.,Zhdankin, V. V.

, p. 2236 - 2238 (2007/10/02)

The role of successive 1,2-hydride shifts in the isomerization processes of cycloalkylcarbonium ions was demonstrated for the case of the alkylation of isomeric methylcyclopentanols or methylcyclopentenes in the presence of sulfuric acid and the isomerization of cyclohexene at acidic aluminum oxide.
