Check Digit Verification of cas no
The CAS Registry Mumber 412319-15-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,1,2,3,1 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 412319-15:
(8*4)+(7*1)+(6*2)+(5*3)+(4*1)+(3*9)+(2*1)+(1*5)=104
104 % 10 = 4
So 412319-15-4 is a valid CAS Registry Number.

Synthesis of 3- and 5-alkyl-6-alkyl(aryl)tetrahydropyran-2,4-diones by the condensation of β-oxo acid esters with aldehydes and ketones
Lokot',Pashkovskii,Lakhvich
, p. 707 - 714 (2001)
A method is proposed for obtaining 3- and 5-alkyl-6-alkyl(aryl)tetrahydropyran-2,4-diones based on the condensation of the dianion of alkyl(dialkyl)acetoacetic ester with aldehydes and ketones.
