Check Digit Verification of cas no

The CAS Registry Mumber 90946-83-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,9,4 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90946-83:
(7*9)+(6*0)+(5*9)+(4*4)+(3*6)+(2*8)+(1*3)=161
161 % 10 = 1
So 90946-83-1 is a valid CAS Registry Number.

A different role of Meldrum's acid in the Biginelli reaction

Svetlik, Jan,Veizerova, Lucia

experimental part, p. 199 - 205 (2011/04/17)

A Biginelli-type condensation using Meldrum's acid has been accomplished in refluxing AcOH to give 6-substituted dihydropyrimidine-2,4-(1H,3H)-diones. In contrast to other aldehydes, the three-component reaction with salicylaldehyde led to an oxygen-bridged pyridine. A reaction mechanism is proposed.
