111425-71-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111425-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,4,2 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 111425-71:
(8*1)+(7*1)+(6*1)+(5*4)+(4*2)+(3*5)+(2*7)+(1*1)=79
79 % 10 = 9
So 111425-71-9 is a valid CAS Registry Number.

A NOVEL FORMATION OF 1,2,3-BUTATRIENE EPISULFIDES BY THIONATION OF METHYLENECYCLOPROPANONES
Ando, Wataru,Hayakawa, Hiroshi,Tokitoh, Norihiro
, p. 1803 - 1806 (2007/10/02)
Sterically hindered methylenecyclopropanones were thionated with phosphorus pentasulfide in pyridine to afford novel 1,2,3-butatriene episulfides and thiiranoradialene derivative via methylenecyclopropanethione intermediate.
