Check Digit Verification of cas no
The CAS Registry Mumber 83505-34-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,0 and 5 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 83505-34:
(7*8)+(6*3)+(5*5)+(4*0)+(3*5)+(2*3)+(1*4)=124
124 % 10 = 4
So 83505-34-4 is a valid CAS Registry Number.

Photochemical rearrangement of 2-(N-allyl-N-alkylamino)cyclohex-2-enones
Meyer, Catherine,Pete, Jean-Pierre,Piva, Olivier
, p. 492 - 497 (2007/10/03)
Irradiation at 366 nm of 2-(N-allyl-N-alkylamino)cyclohex-2-enones led, surprisingly, to very unstable 1-azaspirooctan-4-ones rather than to the expected intramolecular photocycloaddition.The corresponding alcohols could be isolated in good y
