Check Digit Verification of cas no

The CAS Registry Mumber 1645294-11-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,5,2,9 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1645294-11:
(9*1)+(8*6)+(7*4)+(6*5)+(5*2)+(4*9)+(3*4)+(2*1)+(1*1)=176
176 % 10 = 6
So 1645294-11-6 is a valid CAS Registry Number.

Gold-catalyzed tandem reaction of 2-alkynylanilines followed by 1,6-conjugate addition to: P -quinone methides: Efficient access to unsymmetrical diarylindolylmethanes

Jillella, Raveendra,Oh, Dong Hwan,Oh, Chang Ho

, p. 16886 - 16890 (2018)

A simple, mild, efficient and chemoselective catalytic method for the straightforward synthesis of an interesting class of 2-aryl/alkyl-substituted-3-diaryl indolyl methanes in high yield is reported. This atom-efficient method proceeds via a gold-catalyzed one-pot sequential intramolecular hydroamination (C-N bond formation) of 2-alkynylanilines followed by a 1,6-conjugate addition to p-quinonemethides. The p-quinonemethides, which contain aldehyde functional groups, preferentially participate in 1,6-conjugate addition, while the aldehyde functional group remains unreactive.
