Check Digit Verification of cas no

The CAS Registry Mumber 68205-96-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,2,0 and 5 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 68205-96:
(7*6)+(6*8)+(5*2)+(4*0)+(3*5)+(2*9)+(1*6)=139
139 % 10 = 9
So 68205-96-9 is a valid CAS Registry Number.

Ring closure reactions of azidouracils to oxazolo- and isoxazolopyrimidines [1]

Van Tinh, Dang,Stadlbauer, Wolfgang

, p. 1025 - 1030 (2007/10/03)

Thermolysis of 6-azidouracils 1 in the presence of polyphosphoric acid leads either to oxazolo[5,4-d]pyrimidine-5,7-diones 5 (by reaction with benzoic acid 2a) or to isoxazolo[3,4-d]pyrimidine-4,6-diones 7 (by reaction with aliphatic carboxylic acids 2b,c
