113502-91-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113502-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,5,0 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 113502-91:
(8*1)+(7*1)+(6*3)+(5*5)+(4*0)+(3*2)+(2*9)+(1*1)=83
83 % 10 = 3
So 113502-91-3 is a valid CAS Registry Number.

THE REACTION OF α-CHLORO-α-PHENYLTHIOKETONES WITH PHENOLS: AN ALTERNATIVE SYNTHESIS OF BENZOFURANS
Lee, Thomas V.,Galan, Adam A.,Chapleo, Christopher B.
, p. 2301 - 2302 (2007/10/02)
A new synthesis of benzofurans has been developed using the Lewis acid catalysed reaction of readily available α-chloro-α-phenylthioketones with phenols.
