Check Digit Verification of cas no

The CAS Registry Mumber 875431-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,5,4,3 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 875431-05:
(8*8)+(7*7)+(6*5)+(5*4)+(4*3)+(3*1)+(2*0)+(1*5)=183
183 % 10 = 3
So 875431-05-3 is a valid CAS Registry Number.

A novel strategy for the convergent synthesis of 1,3,5,...-polyols: Enone formation, asymmetric dihydroxylation, reductive cleavage, hydride addition

K?rber, Karsten,Risch, Philippe,Brückner, Reinhard

, p. 2905 - 2910 (2005)

Asymmetric dihydroxylation of α,β-unsaturated ketones provided α,β-dihydroxyketones with up to 100% ee. The Cα-O bond of these intermediates or their bis-TMS ethers, acetonides, phenylborates or orthoformiates was cleaved with SmI2, affording β-hydroxyketones. The latter can be reduced to furnish syn- or anti-configured 1,3-diols of any desired configuration. Georg Thieme Verlag Stuttgart.
