Check Digit Verification of cas no

The CAS Registry Mumber 124482-22-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,4,8 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 124482-22:
(8*1)+(7*2)+(6*4)+(5*4)+(4*8)+(3*2)+(2*2)+(1*2)=110
110 % 10 = 0
So 124482-22-0 is a valid CAS Registry Number.

Synthesis and Stereochemistry of Stereoisomeric 1,3-Oxazino- and 1,3-Thiazinoisoquinolines

Fueloep, Ferenc,Bernath, Gabor,El-Gharib, M. S.,Kobor, Jenoe,Sohar, Pal,et al.

, p. 803 - 809 (2007/10/02)

Starting from the 6,7-dialkoxy-1--1,2,3,4-tetrahydroisoquinolines 2 and 3, the 4-imino-substituted 1-(hydroxymethyl)-9,10-dialkoxy-2H,4H-1,6,7,11b-tetrahydro-1,3-oxazino- and -thiazinoisoquinoline diastereomers 6a-c, 7a-c, 8a-c, 9a-c, 14, and 15 and the 4-substituted 1,6,7,11b-tetrahydro-1,3-oxazinoisoquinoline diastereomers 16-24 were prepared.The relative configurations and the predominant conformation of these products were determined by NMR spectroscopy and for 18 by X-ray diffraction methods.The prepared 1,3-oxazinoisoquinoline diastereomers have predominantly trans conformations (16, 18, 22, 23), whereas cis conformations (cis-A) prevail for 20, 21 and 24.Thus, the first evidence for either trans- or cis-A conformations in 1,3-oxazinoisoquinolines is presented.
