1189369-93-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1189369-93-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,3,6 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1189369-93:
(9*1)+(8*1)+(7*8)+(6*9)+(5*3)+(4*6)+(3*9)+(2*9)+(1*3)=214
214 % 10 = 4
So 1189369-93-4 is a valid CAS Registry Number.

Gold(III) bromide catalyzed furannulation of 2-alkynylcycloalk-2-enols: An expedient route to fused furans
Praveen,Kiruthiga,Perumal
, p. 1990 - 1996 (2009)
An efficient synthesis of fused furans from 2-alkynylcycloalk-2-enols via gold(III) bromide catalyzed cycloisomerization was achieved. The reaction condition is moderate and amenable to structurally diverse substrates, leading to good yield of products. G
