1072912-64-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1072912-64-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,7,2,9,1 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1072912-64:
(9*1)+(8*0)+(7*7)+(6*2)+(5*9)+(4*1)+(3*2)+(2*6)+(1*4)=141
141 % 10 = 1
So 1072912-64-1 is a valid CAS Registry Number.

N-heterocyclic carbene induced cycloaddition reactions of indazoles with acetylenes to form a new ring system

Schmidt, Andreas,Snovydovych, Bohdan,Hemmen, Sascha

, p. 4313 - 4319 (2008)

Thermal decarboxylation of the mesomeric betaine 1,2-dimethylindazolium-3- carboxylate resulted in the formation of the N-heterocyclic carbene indazol-3-ylidene which deprotonated a second molecule of the betaine to give an azomethine ylide. This 1,3-dipole underwent a cycloaddition/decarboxylation sequence on treatment with ethyl or methyl 3-phenylpropiolate to give the new ring system 3,5-dihydro-2H-pyrrolo[1,2-b]indazole. By contrast, dimethyl or diethyl but-2-ynedioate (DMAD, DEAD) as the activated triple bond yielded this ring system with an ester group at the 9b-position, which originates from the acetylene derivative. Model reactions were carried out to elucidate the mechanisms of these reactions, and some trapping products of the N-heterocyclic carbene have been characterized.
