Check Digit Verification of cas no

The CAS Registry Mumber 157175-87-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,1,7 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 157175-87:
(8*1)+(7*5)+(6*7)+(5*1)+(4*7)+(3*5)+(2*8)+(1*7)=156
156 % 10 = 6
So 157175-87-6 is a valid CAS Registry Number.

Ligand-free CuTC-catalyzed N-arylation of amides, anilines and 4-aminoantipyrine: Synthesis of N-arylacrylamides, 4-amido-N-phenylbenzamides and 4-amino(N-phenyl)antipyrenes

, p. 81 - 85 (2014/02/14)

N-Arylation of amides and anilines with aryl iodides was efficiently catalyzed by copper thiophenecarboxylate under ligand-free conditions with good to excellent yields. A variety of substituted aryl iodides, amides, anilines and 4-aminoantipyrine were found to be applicable to the simple catalytic system. Furthermore, some practical, unique secondary amides, such as N-arylacrylamides and 4-amido-N-phenylbenzamides, and 4-amino(N-phenyl)antipyrenes, which are difficult to obtain by the classical methods, were prepared.
