Check Digit Verification of cas no

The CAS Registry Mumber 862190-33-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,1,9 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 862190-33:
(8*8)+(7*6)+(6*2)+(5*1)+(4*9)+(3*0)+(2*3)+(1*3)=168
168 % 10 = 8
So 862190-33-8 is a valid CAS Registry Number.

Synthesis of 2-fluoro-11-hydroxy-N-propylnoraporphine: A potential dopamine D2 agonist

Zhang, Ao,Csutoras, Csaba,Zong, Rushi,Neumeyer, John L.

, p. 3239 - 3242 (2005)

(Chemical Equation Presented) 2-Fluoro-11-hydroxy-N-propylnoraporphine 4 (2-F-11 -OH-NPa) was synthesized from thebaine in 13 steps with an overall yield of 1.35%. The key steps included the Pd-catalyzed 3-dehydroxylation of 14-hydroxymorphine, SN2 substitution of Ts- by F -, and CH3SO2OH-promoted rearrangement of the substituted morphinandiene. The dopamine binding affinity of this compound was also investigated on rat brain membranes, and as expected, this compound displayed high affinity and selectivity at the D2 receptor.
