Check Digit Verification of cas no

The CAS Registry Mumber 86509-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,5,0 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 86509-89:
(7*8)+(6*6)+(5*5)+(4*0)+(3*9)+(2*8)+(1*9)=169
169 % 10 = 9
So 86509-89-9 is a valid CAS Registry Number.

Intramolecular Reactions of o-Alkoxy- and o-Alkylthio-benzyl Radicals

Cadogan, J. I. G.,Husband, James B.,McNab Hamish

, p. 697 - 702 (2007/10/02)

We report new gas-phase reactions of o-substituted benzyl radicals produced by flash vacuum pyrolysis of 2,3-dihydro-1,3,2-benzoxazaphosph(V)oles (4)-(6), dibenzyl sulphone (8), and dibenzyl oxalates (9)-(11).Both o-ethoxy- and o-methoxy-benzyl radicals rearrange to o-tolualdehyde via intramolecular hydrogen transfer, as shown by experiments using 2-methoxybenzyl radicals. o-Methylthiobenzyl radicals do not give the corresponding thioaldehyde, but produce a mixture of benzocyclobutene and isomeric dihydrobenzothiophens by novel rearrangement reactions. o-Ethylthio- and o-propylthio-benzyl radicals give o-methylstyrene and o-propenyltoluenes respectively as major products.
