144180-71-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144180-71-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,1,8 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 144180-71:
(8*1)+(7*4)+(6*4)+(5*1)+(4*8)+(3*0)+(2*7)+(1*1)=112
112 % 10 = 2
So 144180-71-2 is a valid CAS Registry Number.

Reductive Cyclization of Quinone Methides
Angle, Steven R.,Rainier, Jon D.
, p. 6883 - 6890 (2007/10/02)
The first use of reduced quinone methides for the formation of carbon-carbon bonds in cyclization reactions is described.Treatment of quinone methides with SmI2 resulted in intramolecular reaction with internal activated multiple bonds to afford 5- and 6-
