125974-08-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125974-08-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,9,7 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 125974-08:
(8*1)+(7*2)+(6*5)+(5*9)+(4*7)+(3*4)+(2*0)+(1*8)=145
145 % 10 = 5
So 125974-08-5 is a valid CAS Registry Number.

Synthesis of chlorinated 5-hydroxy 4-methyl-2(5H)-furanones and mucochloric acid
Franzen, Robert
, p. 3905 - 3908 (2007/10/02)
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.
