Check Digit Verification of cas no

The CAS Registry Mumber 251640-07-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,6,4 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 251640-07:
(8*2)+(7*5)+(6*1)+(5*6)+(4*4)+(3*0)+(2*0)+(1*7)=110
110 % 10 = 0
So 251640-07-0 is a valid CAS Registry Number.

Some synthetic applications of 2,3-dichloro-N-phenylmaleimide: A novel synthesis of 2-phenylpyrrolo[3,4-b]quinoxaline-1,3-diones. I

Hanaineh-Abdelnour, Leila,Bayyuk, Shibly,Theodorie, Rima

, p. 11859 - 11870 (1999)

2,3-Dichloro-N-phenylmaleimide 2 undergoes nucleophilic substitution reactions by a variety of nucleophiles giving either monosubstituted 5 or disubstituted 3 products. Treatment of 5 with sodium azide at room temperature results in cyclization to the corresponding 2-phenylpyrrolo[3,4- b]quinoxaline-1,3-diones 6, while at higher temperatures 5 is reduced to the 2-amino-amino-N-phenylmaleimides 7.
