Check Digit Verification of cas no
The CAS Registry Mumber 161126-13-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,1,2 and 6 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 161126-13:
(8*1)+(7*6)+(6*1)+(5*1)+(4*2)+(3*6)+(2*1)+(1*3)=92
92 % 10 = 2
So 161126-13-2 is a valid CAS Registry Number.

A very convenient, one-pot synthesis (over 80% yield) of 3-bromo-1,5- and -1,7-azulenequinones has been developed by bromination of azulene in aqueous tetrahydrofuran. Reduction of 3-bromo-1,5- and -1,7-azulenequinones with tin or zinc powder in acetic acid gave the parent 1,5- and 1,7-azulenequinones, and further reduction products.
