391906-66-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 391906-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,1,9,0 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 391906-66:
(8*3)+(7*9)+(6*1)+(5*9)+(4*0)+(3*6)+(2*6)+(1*6)=174
174 % 10 = 4
So 391906-66-4 is a valid CAS Registry Number.

The studies of the intramolecular C-F---H-N hydrogen bonding using covalently-linked base pair models of F and A
Shibata,Das,Harada,Takeuchi,Bando
, p. 1755 - 1758 (2007/10/03)
Both 1H NMR and X-ray studies revealed that C-F---H-N intramolecular hydrogen bonding is not observed even in covalently-linked base pair models of F and A. These results strongly support the Kool's hypothesis.
