1254475-89-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1254475-89-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,4,7 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1254475-89:
(9*1)+(8*2)+(7*5)+(6*4)+(5*4)+(4*7)+(3*5)+(2*8)+(1*9)=172
172 % 10 = 2
So 1254475-89-2 is a valid CAS Registry Number.

Synthesis and chemistry of 2-phosphafurans
Duffy, Matthew P.,Lin, Yuhan,Ho, Feny,Mathey, Francois
, p. 5757 - 5758 (2011/01/12)
The reaction between (chlorophosphinidene)pentacarbonyltungsten and benzylideneacetophenone affords a [4 + 1] adduct whose dehydrochlorination by N-methylimidazole affords a 2-phosphafuran complex. Upon further reaction, the phosphafuran is displaced from
