127727-15-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127727-15-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,2 and 7 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 127727-15:
(8*1)+(7*2)+(6*7)+(5*7)+(4*2)+(3*7)+(2*1)+(1*5)=135
135 % 10 = 5
So 127727-15-5 is a valid CAS Registry Number.

Synthesis and NMDA receptor binding of 2-amino-7,7-difluoro-7-phosphonoheptanoic acid
Bigge,Drummond,Johnson
, p. 7013 - 7016 (1989)
In an NMDA specific receptor binding assay, 1 had lower affinity than its parent, APH. This result suggests that for competitive antagonists, diionization of the phosphonic acid moiety may be detrimental to receptor affinity.
