75949-27-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75949-27-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,9,4 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75949-27:
(7*7)+(6*5)+(5*9)+(4*4)+(3*9)+(2*2)+(1*7)=178
178 % 10 = 8
So 75949-27-8 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
