498-19-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 498-19-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,9 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 498-19:
(5*4)+(4*9)+(3*8)+(2*1)+(1*9)=91
91 % 10 = 1
So 498-19-1 is a valid CAS Registry Number.

Synthesis of L-(+)-selenomethionine
Koch,Buchardt
, p. 1065 - 1067 (2007/10/02)
A novel three-pot synthesis of L-(+)-selenomethionine suitable for small and large scale preparations is presented. The method gives high optical purity and avoids evil smelling selenium species.
