Check Digit Verification of cas no

The CAS Registry Mumber 67005-18-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,0,0 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 67005-18:
(7*6)+(6*7)+(5*0)+(4*0)+(3*5)+(2*1)+(1*8)=109
109 % 10 = 9
So 67005-18-9 is a valid CAS Registry Number.

Microwave-expedited one-pot, two-component, solvent-free synthesis of functionalized pyrimidines

Goswami, Shyamaprosad,Jana, Subrata,Dey, Swapan,Kumar Adak, Avijit

, p. 120 - 123 (2007)

The synthesis of a series of diversely substituted pyrimidines under solvent-free conditions in good yields is described. Under microwave irradiation, a variety of nucleophilic substrates containing the N?C?N unit with ?-dicarbonyl compounds, ethyl cyanoacetate, malononitrile, and chalcones was cyclized to give pyrimidines. A combinatorial type approach for a one-step synthesis has been developed where a ring-closing condensation is followed by spontaneous aromatization to afford 28 functionalized and aryl/alkyl substituted pyrimidines.
