34881-13-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34881-13-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,8,8 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 34881-13:
(7*3)+(6*4)+(5*8)+(4*8)+(3*1)+(2*1)+(1*3)=125
125 % 10 = 5
So 34881-13-5 is a valid CAS Registry Number.

Failure of aminophosphonate synthesis due to facile hydroxyphosphonate-phosphate rearrangement
Gancarz,Gancarz
, p. 145 - 148 (1993)
In a Kabachnik-Fields synthesis of aminophosphonates amines can catalyse the formation of hydroxyphosphonates, and their further rearrangement to phosphates, unabling the formation of aminophosphonates.
