Check Digit Verification of cas no

The CAS Registry Mumber 1228358-90-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,3,5 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1228358-90:
(9*1)+(8*2)+(7*2)+(6*8)+(5*3)+(4*5)+(3*8)+(2*9)+(1*0)=164
164 % 10 = 4
So 1228358-90-4 is a valid CAS Registry Number.

Ambient-temperature cobalt-catalyzed cycloaddition strategies to aromatic boronic esters

Auvinet, Anne-Laure,Harrity, Joseph P. A.,Hilt, Gerhard

supporting information; experimental part, p. 3893 - 3896 (2010/08/06)

Figure presented The room-temperature cobalt-catalyzed [4 + 2] cycloaddition of alkynylboronates and 1,3-dienes provides a convenient and general method for the synthesis of benzene-based aromatic boronic esters. Two complementary aromatization strategies involving in situ elimination and DDQ oxidation were explored, with the latter finding more generality. Finally, the potential of this technique to generate highly functionalized biaryls has been demonstrated via the synthesis of chiral (racemic) DMAP catalysts.
