Check Digit Verification of cas no
The CAS Registry Mumber 645393-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,5,3,9 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 645393-95:
(8*6)+(7*4)+(6*5)+(5*3)+(4*9)+(3*3)+(2*9)+(1*5)=189
189 % 10 = 9
So 645393-95-9 is a valid CAS Registry Number.

Studies on the synthesis of (-)-gymnodimine. Subunit synthesis and coupling
White, James D.,Quaranta, Laura,Wang, Guoqiang
, p. 1717 - 1728 (2007/10/03)
Two principal subunits of the marine algal toxin (-)-gymnodimine were synthesized. A trisubstituted tetrahydrofuran representing C10-C18 of the toxin was prepared via a highly stereoselective iodine-mediated cyclization of an acyclic alkene bearing a bis-
