Check Digit Verification of cas no
The CAS Registry Mumber 1057670-01-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,7,6,7 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1057670-01:
(9*1)+(8*0)+(7*5)+(6*7)+(5*6)+(4*7)+(3*0)+(2*0)+(1*1)=145
145 % 10 = 5
So 1057670-01-5 is a valid CAS Registry Number.

A copper-catalyzed multicomponent reaction of sulfonyl azides, alkynes, and allylamines affording 2,3-dihydro-1 H-imidazo-[1,2-a]indoles in moderate yields is reported. Four C-N bonds are constructed- by way of azide-alkyne cycloaddition (CuAAC) and double Ullmann-type coupling reactions in a one-pot process.
