Check Digit Verification of cas no

The CAS Registry Mumber 103516-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,5,1 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 103516-56:
(8*1)+(7*0)+(6*3)+(5*5)+(4*1)+(3*6)+(2*5)+(1*6)=89
89 % 10 = 9
So 103516-56-9 is a valid CAS Registry Number.

Reactions of Uracils, 7. Synthesis and Novel Consecutive Thermal -Sigmatropic Rearrangements of 6-(Alkylamino)-5-ethenyluracils

Matyus, Peter,Zolyomi, Gabor,Eckhardt, Gert,Wamhoff, Heinrich

, p. 943 - 949 (2007/10/02)

Additional 6-(alkylamino)-5-ethenyluracils (2d, 7) have been prepared for investigating substituent effects in thermal reactions.Like 2a, upon heating in Dowtherm A 2d and 7 afford after saponification 6-amino-5-(ethoxycarbonylethyl)uracils 4 and 8, respectively.After refluxing in xylene the intermediary imines 11 and 12 can be isolated.Deuteration experiments reveal consecutive thermal H-migrations (2a-D1 -> 4-D1 and 4-D2; 2a'-D2 -> 4'-D1).The mechanism is discussed.
