111436-86-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111436-86-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,4,3 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 111436-86:
(8*1)+(7*1)+(6*1)+(5*4)+(4*3)+(3*6)+(2*8)+(1*6)=93
93 % 10 = 3
So 111436-86-3 is a valid CAS Registry Number.

A NOVEL, ONE-STEP ANNULATION PROCESS FOR THE SYNTHESIS OF RING-FUSED 2-CYCLOPENTENONES
Corey, E. J.,Su, Wei-guo
, p. 5241 - 5244 (2007/10/02)
The reaction of the dilithio derivative of dimethyl cis-4-cyclohexen-1,2-dicarboxylate with 3-substitued propiolic acid phenyl esters proceeds via an unusual mechanistic path to generate fused bicyclic 2-cyclopentanones in a single step.
