Check Digit Verification of cas no

The CAS Registry Mumber 114091-85-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,0,9 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 114091-85:
(8*1)+(7*1)+(6*4)+(5*0)+(4*9)+(3*1)+(2*8)+(1*5)=99
99 % 10 = 9
So 114091-85-9 is a valid CAS Registry Number.

An efficient synthesis of 2-bromo-3-hydroxy esters by reaction of ketones with ethyl dibromoacetate promoted by samarium diiodide

Concellon, Jose M.,Concellon, Carmen,Diaz, Pamela

, p. 2197 - 2200 (2007/10/03)

A simple and efficient samarium diiodide mediated synthesis of 2-bromo-3-hydroxy esters 1 by the reaction of a variety of ketones 2 with ethyl dibromoacetate (3) is described. The relative configuration of the major diastereoisomer obtained was established by NOESY experiments of the corresponding α,β-epoxy esters 4 prepared from 1. Additionally, a mechanism is proposed to explain the results obtained. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
