Check Digit Verification of cas no
The CAS Registry Mumber 38962-61-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,9,6 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 38962-61:
(7*3)+(6*8)+(5*9)+(4*6)+(3*2)+(2*6)+(1*1)=157
157 % 10 = 7
So 38962-61-7 is a valid CAS Registry Number.

Syntheses of Sulfonated Derivatives of 4-Fluoroaniline; Synthesis of 2-amino-5-fluorobenzenesulfonic acid (2) was achieved by baking the hydrogen sulfate of 4-fluoroaniline (1).Sulfonation of p-fluoroacetanilide (4) with oleum followed by hydrolysis gave 5-amino-2-fluorobenzenesulfonic acid (3).The same reaction with 1 yielded 3 in an impure state.The structures of 2 and 3 were confirmed by converting the diazonium chlorides derived from 5-fluoro-2-nitroaniline (5) and from 2-fluoro-5-nitroaniline (8) to 5-fluoro-2-nitrobenzenesulfonyl chloride (6) and 2-fluoro-5-nitrobenzenesulfonyl chloride (9), respectively, followed by hydrolysis of 6 to 5-fluoro-2-nitrobenzenesulfonic acid (7), and of 9 to 2-fluoro-5-nitrobenzenesulfonic acid (10), and by final reduction.Compound 10 was also obtained by sulfonation of 1-fluoro-4-nitrobenzene (11) with oleum.
