89614-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89614-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,1 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 89614-45:
(7*8)+(6*9)+(5*6)+(4*1)+(3*4)+(2*4)+(1*5)=169
169 % 10 = 9
So 89614-45-9 is a valid CAS Registry Number.

Dinoflagellate neurotoxins related to saxitoxin: Structures of toxins C3 and C4, and confirmation of the structure of neosaxitoxin
Hall,Darling,Boyer,et al.
, p. 3537 - 3538 (2007/10/02)
By x-ray crystallography of the 11β epimer, toxins C3 and C4 are shown to be 21-sulfo-N-1-hydroxysaxitoxin-11α- and 11β-hydroxysulfate, confirming the position and identity of the 3 substituents which, with the parent compound, form the array of 12 saxitoxins found in Protogonyaulax.
