Check Digit Verification of cas no

The CAS Registry Mumber 90414-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,4,1 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 90414-34:
(7*9)+(6*0)+(5*4)+(4*1)+(3*4)+(2*3)+(1*4)=109
109 % 10 = 9
So 90414-34-9 is a valid CAS Registry Number.

Absolute Stereochemistries of the Aplysiatoxins and Oscillatoxin A

Moore, Richard E.,Blackman, Adrian J.,Cheuk, Chad E.,Mynderse, Jon S.,Matsumoto, Gayle K.,et al.

, p. 2484 - 2489 (2007/10/02)

Optical and proton NMR spectral studies of the aplysiatoxins and derivatives, degradation products of the toxins and an X-ray crystallographic analysis of 19,21-dibromoaplysiatoxin show that the absolute configurations of the ten asymmetric carbons are 3S,4R,7S,9S,10S,11R,12S,15S,29R,30R.The 31-nor compound, oscillatoxin A, has the same absolute stereochemistry at C(3), C(4), C(7), C(9), C(10), C(11), C(12), C(15), and C(29).
