Check Digit Verification of cas no

The CAS Registry Mumber 137433-35-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,3 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137433-35:
(8*1)+(7*3)+(6*7)+(5*4)+(4*3)+(3*3)+(2*3)+(1*5)=123
123 % 10 = 3
So 137433-35-3 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

Rearrangement of 4-Chloro-4-aryl(or alkenyl)cyclobutenones to p-Chlorophenols

Xu, Simon L.,Moore, Harold W.

, p. 4024 - 4026 (2007/10/02)

The synthesis and thermolysis of 4-chloro-4-aryl(or alkenyl)cyclobutenones is described.This results in a general and synthetically useful route to highly substituted chlorophenols and chloronaphthols.The chlorocyclobutenones were prepared from the relate
