Check Digit Verification of cas no

The CAS Registry Mumber 92508-52-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,5,0 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 92508-52:
(7*9)+(6*2)+(5*5)+(4*0)+(3*8)+(2*5)+(1*2)=136
136 % 10 = 6
So 92508-52-6 is a valid CAS Registry Number.

Thermal Transformations of Some 3-Acyl-2-oxo-2H-1-benzopyrans with Acid Anhydrides

Bojilova, Anka,Ivanov, Christo

, p. 731 - 735 (2007/10/02)

The reaction of 3-benzoyl- and 3-acetyl-2-oxo-2H-1-benzopyrans (4 and 5) with acid anhydrides in the presence of sodium acetate or triethylamine has been studied.With propionic, butyric and isobutyric acid anhydrides, 4 affords the rearrangement products 6 and 7, dilactones (8) and benzyl esters (9), whereas with acetic anhydride 6a, 10, 11 and 12 are obtained.The reaction of 5 with acetic and propionic acid anhydrides affords 6e, 8f and 9f.Conversion of 9c into different products under acidic conditions has also been studied.
