Check Digit Verification of cas no

The CAS Registry Mumber 54278-10-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,2,7 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 54278-10:
(7*5)+(6*4)+(5*2)+(4*7)+(3*8)+(2*1)+(1*0)=123
123 % 10 = 3
So 54278-10-3 is a valid CAS Registry Number.

(m.n)-Homorubins: Syntheses and structures

Pfeiffer, William P.,Lightner, David A.

, p. 1777 - 1801 (2015/02/19)

Five new homorubin analogs of bilirubin with their two dipyrrinone components conjoined to (CH2)2, (CH2)3, and (CH2)4 units were synthesized with propionic acid chains shortened to acetic and elongated to butyric, and examined by spectroscopy and molecular mechanics computations for an ability to form conformation-determining hydrogen bonds. With m designating the number of conjoining CH2 units and n indicating the number of CH2 units of the alkanoic acid chains of ( m.n)-homorubins, (2.1)-, (3.2)-, (4.2)-, and (4.3)-homorubins were prepared and compared with previously synthesized (2.2) and (2.3), which adopt intramolecularly hydrogen-bonded conformations in CHCl3.

SYNTHESIS AND UNUSUAL PROPERTIES OF C(10)-gem-DIMETHYL BILIRUBIN ANALOGS

Xie, Meiqiang,Lightner, David A.

, p. 2185 - 2200 (2007/10/02)

The characteristic thermodynamically-favored intramolecularly hydrogen-bonded conformation adopted by bilirubin pigments is destabilized by substituting methyl groups on the C(10) central methylene.These methyl groups impose conformation-destabilizing methyl-methylene non-bonded steric interactions with the propionic acid β-CH2 groups at C(8) and C(12) when the propionic acids are engaged in intramolecular hydrogen bonding with the opposing dipyrrinones.Amphiphilic 10,10-dimethylbilirubins (1) and (2) are found to be more polar, but also more soluble than the parents (3) and (4) in organic solvents; yet, 1H-NMR studies in non-polar solvents indicate that a deformed but folded, intramolecularly hydrogen-bonded conformation is retained.The dimethyl esters of 10,10-dimethylbilirubins 1 and 2 did not exhibit the typical strong tendency of bilirubin dimethyl esters to form intermolecular hydrogen bonds in non-polar solvents such as chloroform and benzene.
