346461-20-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 346461-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,6,4,6 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 346461-20:
(8*3)+(7*4)+(6*6)+(5*4)+(4*6)+(3*1)+(2*2)+(1*0)=139
139 % 10 = 9
So 346461-20-9 is a valid CAS Registry Number.

A survey of suitable protecting groups for the synthesis of hydroxylamines by Mitsunobu reactions
Knight, David W.,Leese, Mathew P.
, p. 2593 - 2595 (2007/10/03)
A variety of protecting groups, commonly associated with peptide synthesis, are suitable for the N,O-protection of hydroxylamine; the resulting reagents are all suitable for N-alkylhydroxylamine synthesis using the Mitsunobu method.
