Check Digit Verification of cas no

The CAS Registry Mumber 103225-09-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,2,2 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 103225-09:
(8*1)+(7*0)+(6*3)+(5*2)+(4*2)+(3*5)+(2*0)+(1*9)=68
68 % 10 = 8
So 103225-09-8 is a valid CAS Registry Number.

Synthesis of Pro-Leu-Gly-NH2 Analogues Modified at the Prolyl Residue and Evaluation of Their Effects on the Receptor Binding Activity of the Central Dopamine Receptor Agonist, ADTN

Johnson, Rodney L.,Rajakumar, G.,Yu, Kuo-Long,Mishra, Ram K.

, p. 2104 - 2107 (2007/10/02)

Several analogues of L-prolyl-L-leucylglycinamide (PLG) were synthesized wherein the prolyl residue was replaced with other heterocyclic amino acid residues.Among the analogues synthesized were D-Pro-Leu-Gly-NH2 (2), 3,4-Pro-Leu-Gly-NH2 (7), and D-Δ3,4-Pro-Leu-Gly-NH2 (8).These analogues were tested for their ability to enhance the binding of the agonist 2-amino-6,7-dihydroxy-1,2,3,4-tetrahydronaphthalene to central dopamine receptors.Analogues 2,3, and 5-7 showed activity comparable to that of PLG, while the tripeptides 4 and 8 were found to be inactive.The results show that the N-terminal prolyl residue of PLG is not essential requirement for this tripeptide's ability to modulate dopamine receptors.
