89665-41-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89665-41-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,6 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89665-41:
(7*8)+(6*9)+(5*6)+(4*6)+(3*5)+(2*4)+(1*1)=188
188 % 10 = 8
So 89665-41-8 is a valid CAS Registry Number.

INTRAMOLECULAR 1,3-DIPOLAR CYCLOADDITIONS TO A FURAN RING
Tsuge, Otohiko,Ueno, Kazunori,Kanemasa, Shuji
, p. 285 - 288 (2007/10/02)
1,3-Dipolar systems derived from o-(2-furylmethyloxy)benzaldehyde undergo an intramolecular cycloaddition to the furan ring, giving the corresponding cycloadducts; this provides the first example for the intramolecular 1,3-dipolar cycloaddition to a furan
