133567-53-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133567-53-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,6 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133567-53:
(8*1)+(7*3)+(6*3)+(5*5)+(4*6)+(3*7)+(2*5)+(1*3)=130
130 % 10 = 0
So 133567-53-0 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
