270928-65-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 270928-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,0,9,2 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 270928-65:
(8*2)+(7*7)+(6*0)+(5*9)+(4*2)+(3*8)+(2*6)+(1*5)=159
159 % 10 = 9
So 270928-65-9 is a valid CAS Registry Number.

Stereochemistry and conformational analysis of hemirubin
Huggins, Michael T.,Lightner, David A.
, p. 1797 - 1810 (2007/10/03)
Intramolecularly hydrogen-bonded analogs of the natural bile pigment, bilirubin, are very scarce. Nuclear Overhauser effect NMR studies of the newest analog, a hemirubin (1), confirms intramolecular hydrogen bonding and a ridge-tile-shaped conformation.
