74173-88-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74173-88-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,7 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74173-88:
(7*7)+(6*4)+(5*1)+(4*7)+(3*3)+(2*8)+(1*8)=139
139 % 10 = 9
So 74173-88-9 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.
