651320-49-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 651320-49-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,1,3,2 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 651320-49:
(8*6)+(7*5)+(6*1)+(5*3)+(4*2)+(3*0)+(2*4)+(1*9)=129
129 % 10 = 9
So 651320-49-9 is a valid CAS Registry Number.

Asymmetric synthesis of (α-amino)phosphonic acid amphiphiles using chiral P-H spirophosphoranes
Dejugnat, Christophe,Etemad-Moghadam, Guita,Rico-Lattes, Isabelle
, p. 1858 - 1859 (2007/10/03)
Chiral P-H spirophosphoranes reacted with long-chain prochiral aldimines and, after selective hydrolysis, afforded (α-amino)phosphonic acid amphiphiles in both enantiopure forms.
