Check Digit Verification of cas no

The CAS Registry Mumber 749-01-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,4 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 749-01:
(5*7)+(4*4)+(3*9)+(2*0)+(1*1)=79
79 % 10 = 9
So 749-01-9 is a valid CAS Registry Number.

Silicon-, germanium-, and tin-containing derivatives of barbital and methyluracil

Gordetsov,Loginova,Zimina,Cherepenikova,Kurskii

, p. 870 - 872 (2005)

1,3-Bis(trimethylsilyl)- and 1,3-bis(tributylstannyl)-5,5-diethylpyrimidine-2,4,6(1H,3H,5H)-triones were synthesized in high yields by the reactions of 5,5-diethyl-2,4,6(1H,3H,5H)-trione (barbital) with hexamethyldisilazane and bis(tributylstannyl) oxide, respectively. The products were reacted with acetyl, benzoyl, and 3-(triethylgermyl)propionyl halides to obtain the corresponding bisacylated pyrimidine derivatives. The reaction of 1-methyluracil with (Bu 3Sn)2O gave 1-methyl-3-(tributylstannyl)pyrimidine-2,4(1H,3H)-dione.
