Check Digit Verification of cas no

The CAS Registry Mumber 133900-78-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,0 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 133900-78:
(8*1)+(7*3)+(6*3)+(5*9)+(4*0)+(3*0)+(2*7)+(1*8)=114
114 % 10 = 4
So 133900-78-4 is a valid CAS Registry Number.

On the Reaction of Some 2H-Pyran-2-one Derivatives with Primary Amines

Kvita, Vratislav,Sauter, Hanspeter,Rihs, Grety

, p. 407 - 416 (2007/10/02)

The versatile reactivity of 6-unsubstituted 2H-pyran-2-ones towards aliphatic and aromatic amines has been studied.It was found that the result of the reaction depends not only on the substitution of 2H-pyran-2-ones and on the structure of amines, but also on the stoichiometric ratio of reacting compounds.
