Check Digit Verification of cas no

The CAS Registry Mumber 58081-06-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,0,8 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 58081-06:
(7*5)+(6*8)+(5*0)+(4*8)+(3*1)+(2*0)+(1*6)=124
124 % 10 = 4
So 58081-06-4 is a valid CAS Registry Number.

SOME GROUP IVB DERIVATIVES OF 1,6-METHANOANNULENE. SYNTHESIS, SUBSTITUENT EFFECTS AND REACTIVITY

Kitching, William,Olszowy, Henry A.,Schott, Inge,Adcock, William,Cox, D. P.

, p. 269 - 284 (2007/10/02)

Certain Group IVB derivatives of 1,6-methanoannulene have been synthesised, and their 13C nuclear magnetic resonance spectra recorded and assigned, to provide a measure of the substituent effects exerted by metalloid-containing groups in this non-benzenoid aromatic system.Comparisons are made with the corresponding naphthalene and some anthracene derivatives.Protiodemetallations of a number of arylsilanes and -stannanes have been examined, and in protiodestannyletion by CH3CO2H/dioxane at 27 deg C (an electrophilic aromatic substitution) the α- (or 2-) posititon of 1,6-methanoannulene is ca. 35 times as reactive as the α (or 1-) position of naphthalene, whereas in protiodesilylation by CF3CO2H/CH3CO2H at 27 deg C it is ca. 700 times the more reactive.
