Check Digit Verification of cas no

The CAS Registry Mumber 90123-46-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,2 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 90123-46:
(7*9)+(6*0)+(5*1)+(4*2)+(3*3)+(2*4)+(1*6)=99
99 % 10 = 9
So 90123-46-9 is a valid CAS Registry Number.

IRIDOIDS: THE TOTAL SYNTHESIS OF THE AGLUCONES OF (+/-)-8-EPILOGANIN AND (+/-)-MUSSAENOSIDE VIA BICYCLOOCTENES

Storme, P.,Callant, P.,Vandewalle, M.

, p. 1019 - 1028 (2007/10/02)

The nitrone-olefin cycloaddition reaction has been used to construct cisfused bicyclooctanes or diquinanes as potential intermediates for C-11 functionalized iridoids.The isoxaolidine 7 was obtained in four steps from the commercially available 2-cyclopentene-1-acetic acid 4.Different functionalized diquinanes 8 to 19 and 22 to 24 have been prepared.As illustrative examples of iridoid synthesis, compounds 21 and 26, the O-methyl protected aglucones of (+/-)-8-epiloganin (2) and (+/-)-mussaenoside (3) have been synthesized starting from the common key-intermediate 11.
