Check Digit Verification of cas no

The CAS Registry Mumber 91236-89-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,2,3 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91236-89:
(7*9)+(6*1)+(5*2)+(4*3)+(3*6)+(2*8)+(1*9)=134
134 % 10 = 4
So 91236-89-4 is a valid CAS Registry Number.

Terpenoids from the Sponge Aplysilla glacialis and Specimens of the Nudibranch Cadlina luteomarginta Found on the Sponge

Tischler, Mark,Andersen, Raymond J.,Choudhary, M. Iqbal,Clardy, Jon

, p. 42 - 47 (1991)

Four new rearranged and/or degraded "spongian" terpenoids and one new "marginatane" diterpenoid have been isolated from the marine sponge Aplysilla glacialis.The structure of cadlinolide A (3) was solved by X-ray diffraction analysis, and the structures of cadlinolide B (4), aplysillolide A (5), aplysillolide B (6), and marginatone (7) were determined by extensive spectroscopic analysis and chemical interconversions.Glaciolide (2), cadlinolide A (3), and tetrahydroaplysulphurin-1 (8) were isolated from skin extracts of specimens of the dorid nudibranch Cadlina luteomarginata found feeding on A. glacialis.
