55120-33-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 55120-33-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,1,2 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 55120-33:
(7*5)+(6*5)+(5*1)+(4*2)+(3*0)+(2*3)+(1*3)=87
87 % 10 = 7
So 55120-33-7 is a valid CAS Registry Number.

13C NMR Study of 3,9-Di(alkylphenoxy)-2,4,8,10-tetraoxa-3,9-diphosphaspiroundecanes

Paatoprsty, V.,Malik, L.,Goljer, I.,Goeghova, M.,Karvas, M.,Durmis, J.

, p. 122 - 126 (1985)

13C NMR chemical shifts and 13C-31P coupling constants of fourteen derivatives from 3,9-di(alkylphenoxy)-2,4,8,10-tetraoxa-3,9-diphosphaspiroundecane and of eight derivatives of the 3.9-dioxo type are reported.All investigated compounds possess a chair conformation with the lone pair or the phosphoryl oxygen in the equatorial position.The alkylphenoxy groups are in a cis position with respect to the lone pair or the phosphoryl oxygen.Conformational changes about the aryl-O bond can be minitored via 31P-O-C-13C couplings and their angular dependence was found to be non-symmetric.
