160855-08-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 160855-08-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,8,5 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 160855-08:
(8*1)+(7*6)+(6*0)+(5*8)+(4*5)+(3*5)+(2*0)+(1*8)=133
133 % 10 = 3
So 160855-08-3 is a valid CAS Registry Number.

A facile preparation of 2- and 5-substituted 3-bromothiophenes
Masquelin,Obrecht
, p. 9387 - 9390 (2007/10/02)
Acetylenic ketones of type 4 and acetylenic acetals of type 6 (Scheme 1) are excellent cyclization precursors for the acid-catalyzed synthesis of various heterocycles. Using this methodology, 5- and 2-substituted 3-bromothiophenes of types 7 and 8 have be
