Check Digit Verification of cas no

The CAS Registry Mumber 1189358-57-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,3,5 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1189358-57:
(9*1)+(8*1)+(7*8)+(6*9)+(5*3)+(4*5)+(3*8)+(2*5)+(1*7)=203
203 % 10 = 3
So 1189358-57-3 is a valid CAS Registry Number.

Ring-closing metathesis as a tool for the efficient preparation of chiral spirocyclic ethers from homoallylic alcohols

Rosenberg, Sara,Leino, Reko

, p. 5305 - 5307 (2009)

The preparation of chiral spirocyclic ethers via allylic etherification/olefin metathesis of homoallylic alcohols is investigated. This reaction sequence transforms the enantiopure substrate alcohols, synthesized by a one-pot asymmetric rhodium-catalyzed
