Check Digit Verification of cas no
The CAS Registry Mumber 389090-47-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,9,0,9 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 389090-47:
(8*3)+(7*8)+(6*9)+(5*0)+(4*9)+(3*0)+(2*4)+(1*7)=185
185 % 10 = 5
So 389090-47-5 is a valid CAS Registry Number.

The reactions of diaminomaleonitrile with isocyanates and either aldehydes or ketones revisited
Booth,Dias,Proenca,Zaki
, p. 8436 - 8441 (2007/10/03)
A reinvestigation of the reactions of urea derivatives of diaminomaleonitrile 2 with aldehydes or ketones in the presence of triethylamine has established that the products of these reactions are not pyrimidino[5,4-d]pyrimidines 9 as previously reported, but 8-oxo-6-carboxamido-1,2-dihydropurines 12, which are oxidized rapidly in air to the corresponding 6-carboxamidopurines 13. Similarly, the reaction of Schiff base derivatives of DAMN 5 with isocyanates in the presence of triethylamine gives the substituted 2-oxoimidazoles 20 and not the pyrimidine derivatives 8 as previously claimed. The compounds 20 cyclize in solution and are easily oxidized to 8-oxopurine-6-carbonitriles 22, which give the same 8-oxopurine-6-carboxamides 13 upon further hydrolysis.
