Check Digit Verification of cas no

The CAS Registry Mumber 462117-73-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,2,1,1 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 462117-73:
(8*4)+(7*6)+(6*2)+(5*1)+(4*1)+(3*7)+(2*7)+(1*3)=133
133 % 10 = 3
So 462117-73-3 is a valid CAS Registry Number.

Syntheses of depsipeptide analogues of the insect neuropeptide proctolin.

Scherkenbeck, Juergen,Plant, Andrew,Stieber, Frank,Loesel, Peter,Dyker, Hubert

, p. 1625 - 1628 (2007/10/03)

Four depsipeptide analogues of the insect neuropeptide proctolin (H-Arg-Tyr-Leu-Pro-Thr-OH) have been prepared, containing a single ester linkage between Arg(1) and Tyr(2), Tyr(2) and Leu(3), and between Pro(4) and Thr(5), respectively. A didepsipentapeptide containing an ester linkage between Tyr(2) and Leu(3) and between Pro(4) and Thr(5), has also been prepared. The depsipeptide 4 is the first example of a backbone-modified proctolin analogue which shows full myotropic activity.
