Check Digit Verification of cas no

The CAS Registry Mumber 1050654-20-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,0,6,5 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1050654-20:
(9*1)+(8*0)+(7*5)+(6*0)+(5*6)+(4*5)+(3*4)+(2*2)+(1*0)=110
110 % 10 = 0
So 1050654-20-0 is a valid CAS Registry Number.

Copper mediated atom transfer radical cyclisations with AIBN

Clark, Andrew J.,Wilson, Paul

, p. 4848 - 4850 (2008)

We have shown that it is possible to mediate a range of 5-exo trig and 5-exo dig atom transfer radical cyclisations of bromoacetamides using 0.1-1 mol % CuBr or CuBr2 in conjunction with 0.1-1 mol % tri(pyridin-2-ylmethyl)amine and 10 mol % AIBN. This equates to a 30-300-fold reduction in the amount of catalyst previously reported for these reactions and allows cyclisation to be carried out with the more oxidatively stable CuBr2 without the requirement of an inert atmosphere.
