125995-87-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125995-87-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,9,9 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 125995-87:
(8*1)+(7*2)+(6*5)+(5*9)+(4*9)+(3*5)+(2*8)+(1*7)=171
171 % 10 = 1
So 125995-87-1 is a valid CAS Registry Number.

Synthesis and Reactions of 2-Pyridylphosphane, 2-C5NH4-PH2
Spiegel, Gerd U.,Stelzer, Othmar
, p. 989 - 993 (2007/10/02)
By reduction of diethyl 2-pyridylphosphonate (1) with LiAlH4 2-pyridylphosphane (2) is accessible in ca. 80percent yield.H/D exchange experiments and acid/base exchange reactions between 2 and PhPHLi show 2 to be a stronger PH acid than PhPH2 and Ph2PH.Si
