Check Digit Verification of cas no

The CAS Registry Mumber 89757-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,5 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 89757-45:
(7*8)+(6*9)+(5*7)+(4*5)+(3*7)+(2*4)+(1*5)=199
199 % 10 = 9
So 89757-45-9 is a valid CAS Registry Number.

Stereochemical Course of the Denitrogenation of Optically Active 9,10-Dihydro-5,6-diazalumibullvalene to Optically Active 3,4-Dihydrosemibullvalene

Askani, Rainer,Andermann, Thomas,Mueller, Karl Michael

, p. 1927 - 1938 (2007/10/02)

Thermal decomposition of optical active diazalumibullvalene derivative (+)-6 gives optical active dihydrosemibullvalene (+)-5.The absolute configurations of optical active 6 and 5 were determined by correlation to tricyclooctanone 9 and 2-cyclopentene-1-a
