1148036-64-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1148036-64-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,8,0,3 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1148036-64:
(9*1)+(8*1)+(7*4)+(6*8)+(5*0)+(4*3)+(3*6)+(2*6)+(1*4)=139
139 % 10 = 9
So 1148036-64-9 is a valid CAS Registry Number.

Gold-catalyzed cycloisomerization of alk-4-yn-1-ones
Belting, Volker,Krause, Norbert
supporting information; experimental part, p. 1221 - 1225 (2009/05/30)
Depending on the substitution pattern and the solvent, the gold-catalyzed cyclization of alk-4-yn-1-ones 1 affords different oxygen heterocycles under mild reaction conditions. Alkynones with one substituent at C-3 undergo a 5-exo-dig cycloisomerization t
