162661-76-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 162661-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,6,6 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 162661-76:
(8*1)+(7*6)+(6*2)+(5*6)+(4*6)+(3*1)+(2*7)+(1*6)=139
139 % 10 = 9
So 162661-76-9 is a valid CAS Registry Number.

Synthesis of biliverdins with stable extended conformations. Part II
Bari, Sara E.,Iturraspe, Jose,Frydman, Benjamin
, p. 2255 - 2266 (2007/10/02)
The synthesis of two hexacyclic and one heptacyclic biliverdin with extended conformations was achieved using base catalyzed intramolecular substitution reactions of 2-chloroethyl biliverdins. The 2-chloroethyl residues were located at selected β-pyrrole
