Check Digit Verification of cas no

The CAS Registry Mumber 4249-12-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,4 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4249-12:
(6*4)+(5*2)+(4*4)+(3*9)+(2*1)+(1*2)=81
81 % 10 = 1
So 4249-12-1 is a valid CAS Registry Number.

Photosensitized Electron Transfer from Azoalkanes: Generation, Fragmentation, and Rearrangement of Radical Cations Structurally Related to Dicyclopentadiene

Adam, Waldemar,Sendelbach, Juergen

, p. 5310 - 5315 (1993)

The azoalkanes 1a-c extrude nitrogen upon photosensitized electron transfer (PET) to yield 1,3-radical cation intermediates 2(.+), which undergo interesting transformations.Electron back transfer (BET) affords the unrearranged housanes 2, but significant
