Check Digit Verification of cas no

The CAS Registry Mumber 885670-25-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,5,6,7 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 885670-25:
(8*8)+(7*8)+(6*5)+(5*6)+(4*7)+(3*0)+(2*2)+(1*5)=217
217 % 10 = 7
So 885670-25-7 is a valid CAS Registry Number.

Synthesis and mass spectrometric analysis of cyclostellettamines H, I, K and L

Grube, Achim,Timm, Christoph,Koeck, Matthias

, p. 1285 - 1295 (2006)

Very recently the new cyclostellettamines H, I, K and L were identified from a Brazilian sponge of the genus Pachychalina. They were isolated together with the known cyclostellettamines A-G in a mixture of only 1.5 mg. To obtain further material for biological investigations, the synthesis of the four new cyclostellettamines has been carried out. Since mass spectrometry plays an essential role in identifying these compounds a systematic analysis of the cyclostellettamines is discussed. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
