178875-14-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 178875-14-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,8,7 and 5 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 178875-14:
(8*1)+(7*7)+(6*8)+(5*8)+(4*7)+(3*5)+(2*1)+(1*4)=194
194 % 10 = 4
So 178875-14-4 is a valid CAS Registry Number.

, p. 702 - 704 (2009)

Oligocycles with a 7-thiabicyclo[2.2.1]hept-5-ene unit have been prepared stereoselectively by cycloaddition of thiophene S-oxides to alkenes and subsequent deoxygenation of the sulfoxy bridge of the cycloadducts with PBr 3.

Lewis Acid Catalysis in the Oxidative Cycloaddition of Thiophenes
