1185249-56-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1185249-56-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,5,2,4 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1185249-56:
(9*1)+(8*1)+(7*8)+(6*5)+(5*2)+(4*4)+(3*9)+(2*5)+(1*6)=172
172 % 10 = 2
So 1185249-56-2 is a valid CAS Registry Number.

Gold-catalyzed [3+3]-annulation of azomethine imines with propargyl esters
Shapiro, Nathan D.,Shi, Yun,Toste, F. Dean
, p. 11654 - 11655 (2009)
(Chemical Equation Presented) The gold-catalyzed [3+3]-cycloaddition reaction of propargyl esters and azomethine imines has been developed. The reaction provides a rapid entry into a wide range of substituted tetrahydropyridazine derivatives from simple s
