Check Digit Verification of cas no

The CAS Registry Mumber 682750-15-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,2,7,5 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 682750-15:
(8*6)+(7*8)+(6*2)+(5*7)+(4*5)+(3*0)+(2*1)+(1*5)=178
178 % 10 = 8
So 682750-15-8 is a valid CAS Registry Number.

Synthesis of Imidazolo Analogues of the Oxidation-Reduction Cofactor Pyrroloquinoline Quinone (PQQ)

Fouchard, David M. D.,Tillekeratne,Hudson, Richard A.

, p. 2626 - 2629 (2007/10/03)

Parallel syntheses of 2-hydro-, 2-methyl-, and 2-methoxycarbonylimidazo-7,9-dimethoxycarbonyl analogues of the oxidation-reduction cofactor pyrroloquinoline quinone [4,5-dihydro-4,5-dioxo-1H-pyrrolo[2,3-f]quinoline-2,7,9-tricarboxylic acid] have been developed. The properties of the imidazolo analogues in relation to the corresponding pyrrole analogues will be important in assessing the origins of catalysis and biological activity in the cofactor, which has recently been shown to be a vitamin.
