42849-28-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 42849-28-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,8,4 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 42849-28:
(7*4)+(6*2)+(5*8)+(4*4)+(3*9)+(2*2)+(1*8)=135
135 % 10 = 5
So 42849-28-5 is a valid CAS Registry Number.

, p. 536 - 539 (2007/10/02)
Four stereoisomers of β-methyllanthionine were synthesized by coupling of N-benzyloxycarbonyl-3-methyl-D-cysteine with β-chloroalanine. 1H NMR analysis and retention time in amino acid analysis were studied on these compounds.
