72324-40-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72324-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,3,2 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 72324-40:
(7*7)+(6*2)+(5*3)+(4*2)+(3*4)+(2*4)+(1*0)=104
104 % 10 = 4
So 72324-40-4 is a valid CAS Registry Number.

Reactions of Meldrum's Acid with Isocyanates and Isothiocyanates
Augustin, Manfred,Guenther, Eckhard
, p. 1005 - 1015 (2007/10/02)
Meldrum's acid (1) reacts with isothiocyanates and LiH as base, yielding after alkylation the ketene-S,N-acetales 3, 4 and 5.Protonation of the lithium-thiolate 2 gives the thioamides 7 with tautomers 8, which can be methylated with diazomethane to 9.From
