Check Digit Verification of cas no

The CAS Registry Mumber 122745-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,7,4 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 122745-91:
(8*1)+(7*2)+(6*2)+(5*7)+(4*4)+(3*5)+(2*9)+(1*1)=119
119 % 10 = 9
So 122745-91-9 is a valid CAS Registry Number.

Synthesis of p-Chlorophenols (and -naphthols) from the Thermal Rearrangement of 4-Chlorocyclobutenones

Xu, Simon L.,Moore, Harold W.

, p. 326 - 338 (2007/10/02)

A systematic study of the reaction of 4-hydroxycyclobutenones with thionyl chloride is reported.A useful model evolves from this study which allows the prediction of the site of chlorination for unsymmetrical examples.The chlorination is envisaged to invo
