98728-75-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 98728-75-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,7,2 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98728-75:
(7*9)+(6*8)+(5*7)+(4*2)+(3*8)+(2*7)+(1*5)=197
197 % 10 = 7
So 98728-75-7 is a valid CAS Registry Number.

Studies of phosphazanes. Part 22. High-field nuclear magnetic resonanace investigation of novel isomeric oxophosphazadienes

Swamy, K. C. Kumara,Krishnamurthy, Setharampattu

, p. 1431 - 1434 (2007/10/02)

The reaction of N3P3(NPPh3)Cl5 with an excess of methoxide yields the 'hydroxy'-derivatives, N3P3(NPPh3)(OMe)4(OH) and N3P3(NPPh3)(OMe)3(OH)2, in addition to the fully methoxylated derivative N3P3(NPPh3)(OMe)5.The analogous reaction of gem-N3P3(NPPh3)(NMe2)Cl4 with methoxide affords N3P3(NPPh3)(NMe2)(OMe)4 and N3P3(NPPh3)(NMe2)(OMe)3(OH).The 'hydroxy'-derivatives exist in their oxophosphaza-tautomeric forms.For the 'monohydroxy'-compounds, the presence of a pair of cis- and trans-oxophosphazadienes is established from 1H and 31P n.m.r. spectroscopic data.
