558481-22-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 558481-22-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,8,4,8 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 558481-22:
(8*5)+(7*5)+(6*8)+(5*4)+(4*8)+(3*1)+(2*2)+(1*2)=184
184 % 10 = 4
So 558481-22-4 is a valid CAS Registry Number.

Efficient synthesis of enantiopure β-amino-γ-keto acids from L-homoserine
Sharma, Anil K.,Hergenrother, Paul J.
, p. 2107 - 2109 (2007/10/03)
(Matrix presented) A variety of β-amino-γ-keto acids were prepared in four steps from commercially available L-homoserine. The reaction sequence is highlighted by a Ni-catalyzed Grignard addition to a N-protected derivative of L-homoserine. One of the β-a
