74235-59-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74235-59-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,3 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74235-59:
(7*7)+(6*4)+(5*2)+(4*3)+(3*5)+(2*5)+(1*9)=129
129 % 10 = 9
So 74235-59-9 is a valid CAS Registry Number.

Bimanes. 10. Photochemical Rearrangement of 1,5-Diazabicycloocta-3,7-diene-2,6-diones (9,10-Dioxa-anti-bimanes)

Kanety, Hannah,Dodiuk, Hanna,Kosower, Edward M.

, p. 207 - 213 (2007/10/02)

1,5-Diazabicycloocta-3,7-diene-2,6-diones (9,10-dioxa-anti-bimanes) rearrange quantitatively on irradiation in the 320 nm absorption band to isomeric lactones, one from symmetrical bimanes and two from unsymmetrical bimanes ("mixed" bimanes).The quantum yield of lactone is often high and depends upon bimane substitution and solvent viscosity.Fast intersystem crossing (Huppert et al.), oxygen inhibition of lactone formation, and efficient formation of lactone via a triplet sensitizer implicate the triplet as a key intermediate.The suggested mechanism of lactoneformation involves a twisted ?-?* triplet.
