Check Digit Verification of cas no

The CAS Registry Mumber 108440-58-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,4,4 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 108440-58:
(8*1)+(7*0)+(6*8)+(5*4)+(4*4)+(3*0)+(2*5)+(1*8)=110
110 % 10 = 0
So 108440-58-0 is a valid CAS Registry Number.

EFFICIENT METALLOPORPHYRIN SYNTHESIS UNDER MILD CONDITIONS USING N-BENZYLPORPHYRINS

Lavallee, David K.,White, Adrian,Diaz, Alan,Battioni, Jean-Paul,Mansuy, Daniel

, p. 3521 - 3524 (2007/10/02)

A general method has been developed for nearly quantitative synthesis of N-benzylporphyrins by use of benzyldiphenylsulfonium tetrafluoroborate.The N-benzylporphyrins (including natural, synthetic, water soluble and non-water soluble porphyrins) insert Cu(II), Co(II), Pd(II) and Ni(II) rapidly and then readily lose the N-benzyl group to give non-N-substituted metalloporphyrins.The reactions of Cu(II), Co(II) and Pd(II) are efficient under mild conditions compatible with biological preparations.
