Check Digit Verification of cas no
The CAS Registry Mumber 143334-88-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,3,3 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 143334-88:
(8*1)+(7*4)+(6*3)+(5*3)+(4*3)+(3*4)+(2*8)+(1*8)=117
117 % 10 = 7
So 143334-88-7 is a valid CAS Registry Number.

CHEMOSELECTIVITY REVERSALS IN QUINOXALINES: THE REACTION OF 5-CHLORO-6-NITROQUINOXALINE WITH NUCLEOPHILES
Nasielski, J.,Moucheron, C.,Nasielski-Hinkens, R.
, p. 491 - 496 (2007/10/02)
5-Chloro-6-nitroquinoxaline 2, made in six steps from 2,3-dichloronitrobenzene, reacts 1) with piperidine to give 6-nitro-5-piperidinoquinoxaline as the only product; 2) with methoxide to give a 95:5 ratio of 5-methoxy-6-nitro- and 5-chloro-6-methoxyquino
