Check Digit Verification of cas no

The CAS Registry Mumber 1253944-03-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,9,4 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1253944-03:
(9*1)+(8*2)+(7*5)+(6*3)+(5*9)+(4*4)+(3*4)+(2*0)+(1*3)=154
154 % 10 = 4
So 1253944-03-4 is a valid CAS Registry Number.

Indium-mediated reaction of 1-bromo-1-nitroalkanes with aldehydes: Access to 2-nitroalkan-1-ols

Soengas, Raquel G.,Estevez, Amalia M.

experimental part, p. 5190 - 5196 (2010/11/02)

A novel method for the preparation of 2-nitroalkan-1-ols by an indium-promoted reaction of bromonitromethane with a variety of aldehydes is reported. The reaction was also performed with 2-bromo-2-nitropropanes to afford 2,2-dialkyl-2-nitroalkan-1-ols. The use of chiral sugar-derived aldehydes furnished the corresponding 2-nitroalkan-1-ols with excellent stereoselectivity. The utility of the novel sugar-derived 2,2-dialkyl-2-nitroalkan-1-ols for the preparation of branched iminosugar derivatives was demonstrated by the preparation of a hydroxymethyl branched polyhydroxylated azepane.
