Check Digit Verification of cas no

The CAS Registry Mumber 446266-95-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,6,2,6 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 446266-95:
(8*4)+(7*4)+(6*6)+(5*2)+(4*6)+(3*6)+(2*9)+(1*5)=171
171 % 10 = 1
So 446266-95-1 is a valid CAS Registry Number.

4-Acyl-2H-thiopyran-3,5(4H,6H)-diones: Synthesis, oxidation, and reaction with amines

Zheldakova,Budnikova,Rubinova,Rubinov

, p. 1772 - 1776 (2003)

Acylation of 2H-thiopyran-3,5(4H,6H)-dione and 2-methyl-2H-thiopyran-3, 5(4H,6H)-dione with acetyl chloride or propionyl chloride afforded the corresponding 4-acyl-2H-thiopyran-3,5(4H,6H)-diones. Oxidation of 4-acetyl-2H-thiopyran-3,5(4H,6H)-dione with m-chloroperoxybenzoic acid gave 4-acetyl-2H-thiopyran-3,5(4H,67H)-dione 1-oxide. 4-Acyl-2H-thiopyran-3,5(4H,6H)- diones and 4-acetyl-2H-thiopyran-3,5(4H,6H)-dione 1-oxide reacted with pyrrolidine, allylamine, and p-anisidine, resulting in formation of the corresponding 4-aminomethylene derivatives.
