462871-54-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 462871-54-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,2,8,7 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 462871-54:
(8*4)+(7*6)+(6*2)+(5*8)+(4*7)+(3*1)+(2*5)+(1*4)=171
171 % 10 = 1
So 462871-54-1 is a valid CAS Registry Number.

An efficient asymmetric synthesis of azetidine 2-phosphonic acids
Agami, Claude,Couty, Fran?ois,Rabasso, Nicolas
, p. 4633 - 4636 (2007/10/03)
Substituted azetidinic 2-phosphonates were prepared in diastereoisomerically and enantiomerically pure form, starting from readily available β-amino alcohols. This synthesis involved a three-step sequence: (i) N-alkylation of the starting amino alcohol wi
