Check Digit Verification of cas no
The CAS Registry Mumber 175728-19-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,7,2 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 175728-19:
(8*1)+(7*7)+(6*5)+(5*7)+(4*2)+(3*8)+(2*1)+(1*9)=165
165 % 10 = 5
So 175728-19-5 is a valid CAS Registry Number.

Synthesis of 2-substituted 1,3-oxazin-6-ones by gas-phase pyrolysis
McNab, Hamish,Withell, Kirsti
, p. 3163 - 3170 (1996)
Acylaminomethylene Meldrum's acid derivatives 5 are prepared either by direct reaction of methoxymethylene Meldrum's acid 4 with primary amides, or by acylation of aminomethylene Meldrum's acid 6. Pyrolysis of the substrates 5 under FVP conditions gives the title compounds 8 in good yields.
