264127-08-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 264127-08-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,4,1,2 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 264127-08:
(8*2)+(7*6)+(6*4)+(5*1)+(4*2)+(3*7)+(2*0)+(1*8)=124
124 % 10 = 4
So 264127-08-4 is a valid CAS Registry Number.

Reactivity of ω-hydroxyalkylphosphinic anilides in cyclisation by intramolecular displacement of the aniline moiety
Collison, Shaun,Harger, Martin J. P.
, p. 28 - 29 (2007/10/03)
A cyclic phosphinate 2 is formed when HO(CH2)n+3P(O)(NHPh)Ph (n = 0 or 1) is treated with acid (P-N bond cleavage); five-membered ring formation (n = 0) is 70 times faster than six in CHCl3 and 50 times faster in MeOH.
