683248-56-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 683248-56-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,3,2,4 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 683248-56:
(8*6)+(7*8)+(6*3)+(5*2)+(4*4)+(3*8)+(2*5)+(1*6)=188
188 % 10 = 8
So 683248-56-8 is a valid CAS Registry Number.

, p. 2351 - 2360 (2007/10/03)
Intramolecular McMurry coupling of dialdehydes derived from xylenyl dibromide and 4-hydroxy benzaldehyde afforded cis-stilbenophanes along with cyclophane diols. Stilbenophanes with a large cavity were also synthesized. Charge transfer complexations of th
