136052-59-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136052-59-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,0,5 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 136052-59:
(8*1)+(7*3)+(6*6)+(5*0)+(4*5)+(3*2)+(2*5)+(1*9)=110
110 % 10 = 0
So 136052-59-0 is a valid CAS Registry Number.

A novel synthesis of 1-aminoalkylphosphonates
Chakraborty,Engel
, p. 1039 - 1046 (1991)
A novel route has been devised for the preparation of a series of 1-aminoalkylphosphonate diesters, precursors to analogues of a-amino acids. The route involves a facile bromine substitution at the 1-position of alkylphosphonate diesters using N-bromosuccinimide, followed by azide ion displacement and catalytic hydrogenolysis.
