Check Digit Verification of cas no

The CAS Registry Mumber 20052-58-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,0,5 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20052-58:
(7*2)+(6*0)+(5*0)+(4*5)+(3*2)+(2*5)+(1*8)=58
58 % 10 = 8
So 20052-58-8 is a valid CAS Registry Number.

REGIOSPECIFIC ALKENYLATION OF PHENOLS BY 1,1-DIMETHYLALLENE PROMOTED BY PLATINUM CATALYSTS

Renzi, Augusto De,Panunzi, Achille,Saporito, Antonio,Vitagliano, Aldo

, p. 993 - 996 (2007/10/02)

1,1-Dimethylallene reacts with phenolic substrates in the presence of catalytic amounts of platinum(II) complexes.A regiospecific C-alkenylation takes place, affording o-isopentenylphenols and 2,2-dimethylchromans.Possible reaction mechanisms are also discussed.

Synthesis of 3-Hydroxy-2,3,4,5-tetrahydro-3-methylbenzoxepins by Ring-closure of Isoprenyl Terminal Epoxides

Baird, Kenneth J.,Grundon, Michael F.

, p. 1820 - 1825 (2007/10/02)

Terminal olefins (13), obtained from reactions of tertiary chlorides (10) with triphenylmethyl-lithium, were converted into epoxides (14); base-induced ring-closure of the latter gave 2-hydroxymethyl-2-methylchromans (15) and 3-hydroxy-2,3,4,5-tetrahydro-3-methylbenzoxepins (17).Dehydration of the tetrahydrobenzoxepin (17a) furnished dihydrobenzoxepins.
