Check Digit Verification of cas no

The CAS Registry Mumber 155587-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,5,8 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 155587-72:
(8*1)+(7*5)+(6*5)+(5*5)+(4*8)+(3*7)+(2*7)+(1*2)=167
167 % 10 = 7
So 155587-72-7 is a valid CAS Registry Number.

Synthesis and characterization of the furo and thieno analogues of the triester of PQQ

Martin,Winkler

, p. 100 - 110 (2007/10/02)

We report here the synthesis and properties of the furo and thieno analogues of 4,5-dihydro-4,5-dioxo-1H-pyrrolo[2,3-f]quinoline-2,7,9-tricarboxylic acid (=PQQ), i.e. the furo- and thieno[2,3-f]quinoline-4,5-quinone (FQQ and TQQ, resp.) derivatives B and C, obtained as triesters. The triester of PQQ derivative A is much more stable than the triesters of B or C, and only the triester of A shows strong activity in nonenzymatic catalytic oxidations.
