Check Digit Verification of cas no

The CAS Registry Mumber 19672-38-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,6,7 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 19672-38:
(7*1)+(6*9)+(5*6)+(4*7)+(3*2)+(2*3)+(1*8)=139
139 % 10 = 9
So 19672-38-9 is a valid CAS Registry Number.

ALKYLATION OF β-DIKETONES THROUGH THEIR Co(II), Co(III) AND Zn(II) COMPLEXES. 1-BROMOADAMANTANE AS ALKYLATING AGENT.

Gonzalez, A.,Gueell, F.,Marquet, J.,Moreno-Manas, M.

, p. 3735 - 3738 (1985)

α-(1-Adamantyl)-β-diketones are now accessible by the alkylation of Co(II) complexes of β-diketones with 1-bromoadamantane.The intermediacy of adamantyl cation is proposed.Co(II), Co(III) and Zn(II) complexes of pentane-2,4-dione react with alkyl halides precursors of stabilized carbenium ions, to give 3-alkylpentane-2,4-diones.
