Check Digit Verification of cas no

The CAS Registry Mumber 220663-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,6,6 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 220663-25:
(8*2)+(7*2)+(6*0)+(5*6)+(4*6)+(3*3)+(2*2)+(1*5)=102
102 % 10 = 2
So 220663-25-2 is a valid CAS Registry Number.

Chiral macrocyclic polyethers incorporating a tetraoxaspiro [5.5]undecane or trioxa, azaspiro [5.5]undecane moiety

Garcia, Christophe,Pointud, Yvon,Jeminet, Georges,Dugat, Denise,Beltran, Jose Luis

, p. 4253 - 4265 (1998)

New macrocyclic polyethers possessing chirality due to a spiro ring junction are prepared from 2,8-dihydroxymethylated (+)- 1,4,7,10- tetraoxaspiro[5.5]undecane 1 and (+)- 1,4,7-trioxa- 10-azaspiro[5.5]undecane 2, both (E,E). N-Functionalization of compounds derived from 2 is also examined. The complexing properties of representative ligands 3, 4, 5 measured by spectrophotometry in THF, for alkaline and alkaline-earth cations, indicate that these spheric positively-charged species are weakly associated.
