Check Digit Verification of cas no
The CAS Registry Mumber 38636-12-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,6,3 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 38636-12:
(7*3)+(6*8)+(5*6)+(4*3)+(3*6)+(2*1)+(1*2)=133
133 % 10 = 3
So 38636-12-3 is a valid CAS Registry Number.

THE FOUR 6-HALO-7-NITROQUINOXALINES

The study of relative nucleofugicities of nitro and halogen in quinoxalines required the synthesis of the four 6-halo-7-nitroquinoxalines 2a-d.The fluoro-, chloro- and bromo-derivatives were made from the commercially available or readily accessible 1,2-diamino-4-halobenzenes, using the nitration of the corresponding p-toluenesulfonamides.This scheme failed in the case of the iodo compound because of extensive nitro-deiodination.The synthesis of 6-iodo-7-nitroquinoxaline was finally achieved from m-fluoroiodobenzene by taking advantage of the high reactivity of fluorine, compared to iodine, in 2,4-dinitrohalobenzenes.
