Check Digit Verification of cas no

The CAS Registry Mumber 143768-75-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,6 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 143768-75:
(8*1)+(7*4)+(6*3)+(5*7)+(4*6)+(3*8)+(2*7)+(1*5)=156
156 % 10 = 6
So 143768-75-6 is a valid CAS Registry Number.

, p. 4337 - 4340 (1992)

Regioselective synthesis of di- and trisubstituted tropones has been attained by utilizing anodic oxidation of cyclohepatatriene systems as the key reaction. This anodic oxidation has also been found to be useful for the regioselective synthesis of mono- and disubstituted azulenes.
