Check Digit Verification of cas no

The CAS Registry Mumber 643768-37-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,3,7,6 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 643768-37:
(8*6)+(7*4)+(6*3)+(5*7)+(4*6)+(3*8)+(2*3)+(1*7)=190
190 % 10 = 0
So 643768-37-0 is a valid CAS Registry Number.

Synthesis and Structural Determination of a Porphyrinatoplatinum(II): Meso-Tetrakis(4-t-butylphenyl)porphyrinatoplatinum(II)

, p. 2123 - 2127 (2003)

A substituted porphyrinatoplatinum(II) meso-tetrakis(4-t-butylphenyl)porphyrinatoplatinum(II), has been spectroscopically and structurally characterized. The 1HNMR signal from the β-protons of the pyrrole ring is observed as a singlet with a full-width at half maximum of 1.6 Hz, contrary to the reported quasi-triplet resonance attributable to the 1H-195Pt long-range coupling. The porphyrin nucleus is nearly planar in the solid state. All macrocycle atoms lie within approximately 0.06 A of the least squares mean plane with a pseudo-wave core conformation. The intramolecular Pt-N distances are 2.019(3) A.
