Check Digit Verification of cas no

The CAS Registry Mumber 121590-75-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,5,9 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121590-75:
(8*1)+(7*2)+(6*1)+(5*5)+(4*9)+(3*0)+(2*7)+(1*5)=108
108 % 10 = 8
So 121590-75-8 is a valid CAS Registry Number.

NEW SKELETAL REARRANGEMENTS VIA A CONSTRAINED CYCLOPROPYLDICARBINYL DIRADICAL GENERATED IN THE PHOTODECARBONYLATION OF 2,4-DIPHENYLTETRACYCLO2,4.03,7>DECA-9-ENE-6,8-DIONE

, p. 5933 - 5936 (2007/10/02)

Photodecarbonylation of the title diketone (1) gave 3,3a-diphenyl-3a,7a-dihydroindenone (2), 1,4-diphenylcyclooctatetraene (3), and 1,6-diphenylcycloheptatrien-7-ylketene (4).The reaction pathways are discussed on proposing intermediates of 1,2-diphenyltetracyclo2,9.05,8>non-3-en-7-one (11) and 1,3-diphenyltricyclo2,9>nona-3,5-dien-8-one (13).Ring expansion of 1 to a 6-membered oxacarbene (17) was also observed.
