Check Digit Verification of cas no
The CAS Registry Mumber 15987-00-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,9,8 and 7 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 15987-00:
(7*1)+(6*5)+(5*9)+(4*8)+(3*7)+(2*0)+(1*0)=135
135 % 10 = 5
So 15987-00-5 is a valid CAS Registry Number.

2,3-Dialkylquinoxalines (4), which are available from the reaction of benzofuroxan (1) with ketones and subsequent reduction of the 2,3-dialkylquinoxaline N,N'-dioxides (3), are converted to 2,3-dialkylpyrazines (6) by oxidation-decarboxylation steps.
