Check Digit Verification of cas no

The CAS Registry Mumber 321903-41-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,9,0 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 321903-41:
(8*3)+(7*2)+(6*1)+(5*9)+(4*0)+(3*3)+(2*4)+(1*1)=107
107 % 10 = 7
So 321903-41-7 is a valid CAS Registry Number.

Regioselectivity in the intramolecular allyl transfer reaction catalysed by electrogenerated nickel complexes: Influence of metal ions

Franco, Delphine,Du?ach, Elisabet

, p. 9289 - 9296 (2002)

The intramolecular transfer of allyl moieties from substituted allyl aryl ethers to carbonyl groups has been studied by electrosynthesis, in a nickel-catalysed reaction. The influence of metal ions such as Mg2+, Zn2+ and Al3+ has been examined. Regioselectivity towards the branched isomer was better with Zn2+ than with Mg2+ ions, but it was higher in the absence of added metal ions.
