81730-30-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81730-30-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,3 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81730-30:
(7*8)+(6*1)+(5*7)+(4*3)+(3*0)+(2*3)+(1*0)=115
115 % 10 = 5
So 81730-30-5 is a valid CAS Registry Number.

A NEW REACTION IN COMPOUNDS OF THE FURAN SERIES
Kharchenko, V. G.,Gubina, T. I.,Markushina, I. A.
, p. 343 - 347 (2007/10/02)
2,5-Dialkylfurans and alcohols, ketones, and esters of the furan series react with hydrogen sulfide under the conditions of acid catalysis and are converted into the corresponding analogs of the thiophene series.A possible reaction mechanism is discussed.
