Check Digit Verification of cas no

The CAS Registry Mumber 1204504-87-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,5,0 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1204504-87:
(9*1)+(8*2)+(7*0)+(6*4)+(5*5)+(4*0)+(3*4)+(2*8)+(1*7)=109
109 % 10 = 9
So 1204504-87-9 is a valid CAS Registry Number.

Tridentate P,N,N-ligand promoted copper-catalyzed [3 + 2] cycloaddition of propargylic esters with β-enamino esters: Synthesis of highly functionalized pyrroles

Li, Qing,Hou, Chuan-Jin,Hui, Yun-Ze,Liu, Yan-Jun,Yang, Rui-Feng,Hu, Xiang-Ping

, p. 85879 - 85883 (2015)

A copper-catalyzed [3 + 2] cycloaddition of propargylic esters with β-enamino esters under mild reaction conditions for the construction of highly functionalized pyrroles has been developed. By employment of a newly developed tridentate P,N,N-ligand, a va

Synthesis of pyrroles by gold(I)-catalyzed amino-claisen rearrangement of N-propargyl enaminone derivatives

Saito, Akio,Konishi, Tomoyo,Hanzawa, Yuji

supporting information; experimental part, p. 372 - 374 (2010/03/25)

(Figure presented) The cationic N-heterocyclic carbene-gold(I) complex catalyzes the formation of tri- and tetrasubstituted pyrroles via the amino-Claisen rearrangement of N-propargyl β-enaminone derivatives and the cyclization of α-allenyl β-enaminone in
