Check Digit Verification of cas no

The CAS Registry Mumber 609369-02-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,0,9,3,6 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 609369-02:
(8*6)+(7*0)+(6*9)+(5*3)+(4*6)+(3*9)+(2*0)+(1*2)=170
170 % 10 = 0
So 609369-02-0 is a valid CAS Registry Number.

Synthesis of β-pyrrole and β-thiophene substituted 21,23-dithia and 21-monothiaporphyrins

Agarwal, Neeraj,Ravikanth, Mangalampalli

, p. 4739 - 4747 (2007/10/03)

A series of β-pyrrole and β-thiophene substituted porphyrins with N2S2 and N3S porphyrin cores were synthesized and characterized. The introduction of substituents at β-pyrrole and β-thiophene carbons resulted in significant shifts in 1H NMR, absorption and fluorescence maxima. These effects were attributed to alteration of the porphyrin ring current caused by substituents at β-positions.
