Check Digit Verification of cas no

The CAS Registry Mumber 91909-63-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,9,0 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 91909-63:
(7*9)+(6*1)+(5*9)+(4*0)+(3*9)+(2*6)+(1*3)=156
156 % 10 = 6
So 91909-63-6 is a valid CAS Registry Number.

THERMOLYTIC RING OPENING OF ACYLOXYBENZOCYCLOBUTENES: AN EFFICIENT ROUTE TO 3-SUBSTITUTED ISOQUINOLINES

Schiess, Peter,Huys-Francotte, Martine,Vogel, Caspar

, p. 3959 - 3962 (1985)

Upon flash vacuum pyrolysis acyloxybenzocyclobutenes 4 rearrange through an intramolecular 1,5-acyl shift to 2-formylbenzyl ketones 6 which can be converted to 3-substituted isoquinolines 7.
