The CAS Registry Mumber 124362-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,3,6 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 124362-40:
(8*1)+(7*2)+(6*4)+(5*3)+(4*6)+(3*2)+(2*4)+(1*0)=99
99 % 10 = 9
So 124362-40-9 is a valid CAS Registry Number.

PORPHYRINS AND THEIR DERIVATIVES. VII. SYNTHESIS OF NEW CROWN-PORPHYRINS AND THEIR PROPERTIES

Zhilina, Z. I.,Mel'nik, V. I.,Andronati, S. A.,Abramovich, A. E.

, p. 957 - 963 (2007/10/02)

The condensation of pyrrole with formylbenzocrown ethers leads to previously unknown meso-tetra(benzo-12-crown-4)- and meso-(benzo-24-crown-8)porphyrins.Condensation with a mixture of aldehydes leads to new crown-porphyrins containing hydrophilic pyridyl and lipophilic nonyl substituents at the meso positions in addition to the crown ether fragments.
