The CAS Registry Mumber 1254063-75-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,0,6 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1254063-75:
(9*1)+(8*2)+(7*5)+(6*4)+(5*0)+(4*6)+(3*3)+(2*7)+(1*5)=136
136 % 10 = 6
So 1254063-75-6 is a valid CAS Registry Number.

Synthesis of regioselectively functionalized benzo[b]thiophenes by combined ortho-lithiation-halocyclization strategies

Sanz, Roberto,Guilarte, Veronica,Hernando, Elsa,Sanjuan, Ana M.

, p. 7443 - 7446 (2010)

An efficient synthesis of 3-halo-7-oxygen-functionalized benzo[b]thiophenes bearing different substituents at C-2 has been developed from N,N-diethyl O-3-halophenylcarbamates. The key steps are an ortho-lithiation reaction, which gives rise to 3-halo-2-su
