Check Digit Verification of cas no
The CAS Registry Mumber 204919-82-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,9,1 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 204919-82:
(8*2)+(7*0)+(6*4)+(5*9)+(4*1)+(3*9)+(2*8)+(1*2)=134
134 % 10 = 4
So 204919-82-4 is a valid CAS Registry Number.

Practical synthesis of Schollkopf's bis-lactim ether chiral auxiliary: (3S)-3,6-dihydro-2,5-dimethoxy-3-isopropyl-pyrazine
Bull, Steven D.,Davies, Stephen G.,Moss, William O.
, p. 321 - 327 (1998)
Practical methodology for the bis-O-methylation of (3S)-isopropyl-piperazine-2,5-dione 4 on a 45 g scale to generate Schollkopf's bis-lactim ether chiral auxiliary (3S)-3,6-dihydro-2,5-dimethoxy-3-isopropyl-pyrazine 1 has been developed. Monomethylated intermediates 5 and 6 are reported for the first time. The gelling effects of 4 in a range of common solvents are also described.
