Check Digit Verification of cas no

The CAS Registry Mumber 49704-72-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,7,0 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 49704-72:
(7*4)+(6*9)+(5*7)+(4*0)+(3*4)+(2*7)+(1*2)=145
145 % 10 = 5
So 49704-72-5 is a valid CAS Registry Number.

Gold-catalyzed [3+2]-annulations of α-aryl diazonitriles with ynamides and allenamides to yield 1-amino-1H-indenes

Singh, Rahulkumar Rajmani,Pawar, Samir Kundlik,Huang, Min-Jie,Liu, Rai-Shung

supporting information, p. 11434 - 11437 (2016/09/23)

Gold-catalyzed [3+2]-annulations of α-aryl diazonitriles with ynamides and allenamides yield 1-amino-1H-indenes in two distinct pathways; the success of these annulations relies on the high electrophilicity of α-cyano arylgold carbenes to activate an ionic pathway.
