Check Digit Verification of cas no

The CAS Registry Mumber 55542-91-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,5,4 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 55542-91:
(7*5)+(6*5)+(5*5)+(4*4)+(3*2)+(2*9)+(1*1)=131
131 % 10 = 1
So 55542-91-1 is a valid CAS Registry Number.

Palladium-catalyzed tandem alkenyl and aryl C-N bond formation: A cascade N-annulation route to 1-functionalized indoles

Willis, Michael C.,Brace, Gareth N.,Holmes, Ian P.

, p. 403 - 406 (2007/10/03)

(Chemical Equation Presented) A single tandem operation allows rapid access to a variety of substituted N-functionalized indoles. The nitrogen atom of the indole nucleus is incorporated through Pd-catalyzed aryl and alkenyl C-N bond-forming reactions (see scheme; dba = dibenzylideneacetone). Amine, aniline, amide, carbamate, and sulfonamide functional groups can be introduced efficiently.
