Check Digit Verification of cas no

The CAS Registry Mumber 500187-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,0,1,8 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 500187-72:
(8*5)+(7*0)+(6*0)+(5*1)+(4*8)+(3*7)+(2*7)+(1*2)=114
114 % 10 = 4
So 500187-72-4 is a valid CAS Registry Number.

From common carbohydrates to enantiopure cyclooctane polyols and glycomimetics via deoxygenative zirconocene ring contraction

Paquette, Leo A.,Zhang, Yunlong

, p. 4353 - 4363 (2007/10/03)

D-Arabinose and D-glucose are transformed into the identical vinyl furanoside, whose role is to serve as the precursor to enantiopure cyclooctadienone 6. The key steps of this relay involve a zirconocene-promoted ring contraction and [3,3] sigmatropic rea

Zirconocene-mediated route to enantiopure 9-oxabicyclononanes functionalized on both carbon bridges

Paquette, Leo A.,Kim, In Ho,Cuniere, Nicolas

, p. 221 - 223 (2007/10/03)

(Matrix presented) A zirconocene-mediated ring contraction of 4-vinylfuranosides generated either from D-arabinose or D-glucose is followed by sequential oxidation to the ketone and alkynyl Grignard addition. The resulting cis-cyclobutanediols are subjected in turn to thermal rearrangement and intramolecular oxymercuration-demercuration. The regiochemistry of the final ring closure is controlled by the nature of R.
