Check Digit Verification of cas no

The CAS Registry Mumber 53151-59-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,1,5 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 53151-59:
(7*5)+(6*3)+(5*1)+(4*5)+(3*1)+(2*5)+(1*9)=100
100 % 10 = 0
So 53151-59-0 is a valid CAS Registry Number.

Radical Addition to the Carbonyl Carbon Promoted by Aqueous Titanium Trichloride: Stereoselective Synthesis of α,β-Dihydroxy Ketones

Clerici, Angelo,Porta, Ombretta

, p. 3872 - 3878 (2007/10/02)

Ketyl radicals, formed by chemoselective Ti(III) reduction of α,β-dicarbonyl compounds, add to the carbonyl carbon of aldehydes under mild conditions to afford α,β-dihydroxy ketones in good to excellent yields.Simple diastereoselectivity strongly depends on the bulk of groups bonded to both the ketyl radical and the aldehydic function.The relative configuration of two the keto diols was established by single-crystal X-ray diffractometry.
