Check Digit Verification of cas no

The CAS Registry Mumber 17539-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,5,3 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 17539-22:
(7*1)+(6*7)+(5*5)+(4*3)+(3*9)+(2*2)+(1*2)=119
119 % 10 = 9
So 17539-22-9 is a valid CAS Registry Number.

Laser flash photolysis study of the reactivity of α-ketenylbenzocyclobutenone with water and alcohols

De Lucas, Nanci Camara,Andraos, John,Netto-Ferreira,Scaiano

, p. 677 - 680 (2007/10/02)

Photolysis of 2-diazo-1,3-indandione leads to ketene formation via the Wolff rearrangement. Ketene 2 hydrates to produce enol 3a that rearranges to 4a. Homophthalic acid 5a is formed by photodecomposition of 4a upon prolonged irradiation.
