Check Digit Verification of cas no

The CAS Registry Mumber 17337-86-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,3,3 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 17337-86:
(7*1)+(6*7)+(5*3)+(4*3)+(3*7)+(2*8)+(1*6)=119
119 % 10 = 9
So 17337-86-9 is a valid CAS Registry Number.

Synthesis, Resolution, and Assignment of Configuration of Potent Hypotensive Retro-inverso Bradykinin Potentiating Peptide 5a(BPP5a) Analogues

Verdini, Antonio S.,Viscomi, Giuseppe C.

, p. 697 - 702 (2007/10/02)

The effect on the the biological activity of an inverted amide group as an isosteric replacement for the Phe-Ala scissile bond of the BPP5a analogue 3>BPP5a has been studied.The synthesis of the retro-inverso pentapeptide 3,(R,S)-mAla4>BPP5a has been carried out in solution by coupling the pseudopeptide epimer HO-(R,S)-mAla-Pro-OBut to Glp-Lys(Boc)-gPhe-H.HCl, separation and identification of the resulting diastereomers 2(Boc),gPhe3,(S)-mAla4,Pro5-OBut>BPP5a and 2(Boc),gPhe3,(R)-mAla4,Pro5-OBut>BPP5a, and finally acidolytic cleavage. 3,(S)-mAla4>BPP5a, a moderate inhibitor of angiotensin converting enzyme (ACE) in vitro (I50=14 x 1E-5), was obtained and proved to be more potent than BPP5a as a hypotensive in normotensive rats without manifesting the bradykinin potentiating action of the natural peptide.
