Check Digit Verification of cas no
The CAS Registry Mumber 120889-35-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,8,8 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 120889-35:
(8*1)+(7*2)+(6*0)+(5*8)+(4*8)+(3*9)+(2*3)+(1*5)=132
132 % 10 = 2
So 120889-35-2 is a valid CAS Registry Number.

The photocycloaddition reactions of uridine and related compounds with 2,3-dimethyl-2-butene

The photochemical reactions of uracil and 5-fluorouracil derivatives with simple alkenes have been investigated. Photocycloaddition of uracil or 5-fluorouracil derivatives and 2,3-dimethyl-2-butene in acetone gave an enantiomeric mixture of cross cycloadducts (4, 7) in moderate yields. Under similar conditions, diastereomers of 4-substituted 7,7,8,8-tetramethyl-cis-2,4-diazabicyclo[4.2.0]octane-3,5-dione nucleosides (14-17) were formed from uridine or 5-fluorouridine derivatives in good yields. The structures and stereochemistry of these cycloadducts of the nucleoside series were elucidated on the basis of the proton nuclear magnetic resonance spectra and X-ray crystallographic analysis.
