Check Digit Verification of cas no

The CAS Registry Mumber 100421-99-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,4,2 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 100421-99:
(8*1)+(7*0)+(6*0)+(5*4)+(4*2)+(3*1)+(2*9)+(1*9)=66
66 % 10 = 6
So 100421-99-6 is a valid CAS Registry Number.

The Formation of Ozonides by Electron Transfer Induced Photo-oxidation of Small-ring Cycloalkenes

Kirschenheuter, Gary P.,Griffin, Gary W.

, p. 596 - 597 (1983)

Several polymethyl-1,2-diphenylcyclobutenes have been subjected to photo-oxidation in acetonitrile in the presence of 9,10-dicyanoanthracene and it is possible to isolate the corresponding ozonides, in moderate yields (ca. 13percent), apparently formed from oxirans produced in a primary step; 1,4-diketones are not generated from the ozonides under the reaction conditions although they are formed as reaction products by what must be an alternative mechanism.
