112309-61-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112309-61-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,3,0 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 112309-61:
(8*1)+(7*1)+(6*2)+(5*3)+(4*0)+(3*9)+(2*6)+(1*1)=82
82 % 10 = 2
So 112309-61-2 is a valid CAS Registry Number.

Synthesis of chlorinated 5-hydroxy 4-methyl-2(5H)-furanones and mucochloric acid
Franzen, Robert
, p. 3905 - 3908 (1995)
An improved procedure for the synthesis of chlorinated 5-hydroxy-4-methyl-2(5H)-furanones is described. By this method also carbon-labelled (13C and 14C at C-3) hydroxyfuranones, including mucochloric acid, can be prepared. Each step of the method was examined in an effort to optimize both the yield and the purity of the compounds.
