60031-34-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 60031-34-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,0,3 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 60031-34:
(7*6)+(6*0)+(5*0)+(4*3)+(3*1)+(2*3)+(1*4)=67
67 % 10 = 7
So 60031-34-7 is a valid CAS Registry Number.

Synthesis of 2(3H)-furanones via electrophilic cyclization
Just, Ziwei W.,Larock, Richard C.
, p. 2662 - 2667 (2008/09/19)
(Chemical Equation Presented) A variety of highly substituted 2(3H)-furanones are readily prepared from 3-alkynoate esters and the corresponding acids via electrophilic cyclization. Successful electrophiles in this process include I2, ICl, and
