Check Digit Verification of cas no
The CAS Registry Mumber 106537-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,5,3 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 106537-89:
(8*1)+(7*0)+(6*6)+(5*5)+(4*3)+(3*7)+(2*8)+(1*9)=127
127 % 10 = 7
So 106537-89-7 is a valid CAS Registry Number.

Synthesis of Some New Pyrimidopyrimidines
Pegiadou-Koemtjopoulou, S.,Tsatsaronis, G.
, p. 335 - 336 (2007/10/02)
4-Amino-5-arylpyrimidines 1 react with diethyl alkylmalonates 2 to give pyrimidopyrimidines 4 in satisfactory yields.A possible mechanistic scheme and the spectral data of the reaction products are discussed.
