175202-53-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 175202-53-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,2,0 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 175202-53:
(8*1)+(7*7)+(6*5)+(5*2)+(4*0)+(3*2)+(2*5)+(1*3)=116
116 % 10 = 6
So 175202-53-6 is a valid CAS Registry Number.

New compounds from 6,7-dihydrobenzo[c]thiophen-4(5H)-ones
Prim, Damien,Joseph, Delphine,Kirsch, Gilbert
, p. 239 - 245 (2007/10/03)
The reactivity of the ketone moiety in 6,7-dihydrobenzo[c]-thiophen-4(5H)-ones 1 was used to generate new benzo[c]-thiophene derivatives. The behaviour of the ketones under Vilsmeier-Haack-Arnold conditions was studied. Generally, the reactivity of the ke
