Check Digit Verification of cas no

The CAS Registry Mumber 162019-03-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,0,1 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 162019-03:
(8*1)+(7*6)+(6*2)+(5*0)+(4*1)+(3*9)+(2*0)+(1*3)=96
96 % 10 = 6
So 162019-03-6 is a valid CAS Registry Number.

SYNTHESIS OF RIGIDLY LINKED TRIAD MOLECULES BASED ON OCTAALKYLPORPHYRIN, CAPABLE OF MULTISTEP ELECTRON TRANSFER

Gribkov, A.A.,Borovkov, V.V.,Evstigneeva, R.P.,Sakata, Y.

, p. 905 - 915 (2007/10/02)

We have designed and carried out the synthesis of triad model systems containing octaalkylporphyrin, benzoquinone, and trichlorobenzoquinone with an oxidation-reduction potential gradient in the molecule.The quinone moieties are fixed relative to the porphyrin using spirononane and methylene spacers.
