Check Digit Verification of cas no

The CAS Registry Mumber 1563242-87-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,3,2,4 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1563242-87:
(9*1)+(8*5)+(7*6)+(6*3)+(5*2)+(4*4)+(3*2)+(2*8)+(1*7)=164
164 % 10 = 4
So 1563242-87-4 is a valid CAS Registry Number.

Isolation and synthesis of pulmonarins A and B, acetylcholinesterase inhibitors from the colonial ascidian Synoicum pulmonaria

Tadesse, Margey,Svenson, Johan,Sepcic, Kristina,Trembleau, Laurent,Engqvist, Magnus,Andersen, Jeanette H.,Jaspars, Marcel,Stensvaisg, Klara,Haug, Tor

, p. 364 - 369 (2014/03/21)

Pulmonarins A and B are two new dibrominated marine acetylcholinesterase inhibitors that were isolated and characterized from the sub-Arctic ascidian Synoicum pulmonaria collected off the Norwegian coast. The structures of natural pulmonarins A and B were tentatively elucidated by spectroscopic methods and later verified by comparison with synthetically prepared material. Both pulmonarins A and B displayed reversible, noncompetitive acetylcholinesterase inhibition comparable to several known natural acetylcholinesterase inhibitiors. Pulmonarin B was the strongest inhibitor, with an inhibition constant (K i) of 20 μM. In addition to reversible, noncompetitive acetylcholinesterase inhibition, the compounds displayed weak antibacterial activity but no cytotoxicity or other investigated bioactivities.
