Check Digit Verification of cas no

The CAS Registry Mumber 1421364-78-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,3,6 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1421364-78:
(9*1)+(8*4)+(7*2)+(6*1)+(5*3)+(4*6)+(3*4)+(2*7)+(1*8)=134
134 % 10 = 4
So 1421364-78-4 is a valid CAS Registry Number.

Coupling of two multistep catalytic cycles for the one-pot synthesis of propargylamines from alcohols and primary amines on a nanoparticulated gold catalyst

Corma, Avelino,Navas, Javier,Sabater, Maria J.

, p. 14150 - 14156 (2013/01/15)

A one-pot reaction was performed with a nanoparticulated gold catalyst. A secondary amine is formed through N-monoalkylation of a primary amine with an alcohol by a borrowing hydrogen methodology in a three-step reaction. The secondary amine formed enters into a second A3-coupling cycle to give propargylamines. The multistep reaction requires a gold species formed and stabilized on a ceria surface. Copyright
