Check Digit Verification of cas no

The CAS Registry Mumber 4211-33-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,1 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4211-33:
(6*4)+(5*2)+(4*1)+(3*1)+(2*3)+(1*3)=50
50 % 10 = 0
So 4211-33-0 is a valid CAS Registry Number.

Isolation and synthesis of tanyolides A and B, metabolites of the nudibranch Sclerodoris tanya

Krug, Patrick J.,Boyd, Kenneth G.,Faulkner, D. John

, p. 11063 - 11074 (2007/10/02)

The nudibranch Sclerodoris tanya, which was collected intertidally at La Jolla, contains two sesquiterpene glyceride esters, tanyolides A (4) and B (5). The structures of the tanyolides were elucidated by interpretation of spectral data. The absolute configuration of tanyolide B (5) was determined by synthesis of both enantiomers and the structure of tanyolide A (4) was also confirmed by synthesis. The tanyolides, which are located primarily in the dorsal mantle, deter feeding by two ecologically-relevant predatory fish.
