76023-03-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76023-03-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,0,2 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 76023-03:
(7*7)+(6*6)+(5*0)+(4*2)+(3*3)+(2*0)+(1*3)=105
105 % 10 = 5
So 76023-03-5 is a valid CAS Registry Number.

Molecular Organization by Hydrogen Bonding: Juxtaposition of Remote Double Bonds for Photocyclization in a 2-Pyridone Dimer
Beak, Peter,Zeigler, John M.
, p. 619 - 624 (2007/10/02)
Irradiation of the hydrogen bonded dimer of 3--6--2-pyridone (1) provides the δ-truxinic acid ester 3 and the β-truxinic acid ester 4, respectively.The photocyclization occurs via a 25-membered ring in yields
