Check Digit Verification of cas no
The CAS Registry Mumber 39205-76-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,2,0 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 39205-76:
(7*3)+(6*9)+(5*2)+(4*0)+(3*5)+(2*7)+(1*6)=120
120 % 10 = 0
So 39205-76-0 is a valid CAS Registry Number.

A method was developed for the synthesis of 5-bromo-1-methyl-4-nitropyrazole from 1-methylpyrazole.In the reaction with 25percent aqueous ammonia at 180-190 deg C, 5-bromo-1-methyl-4-nitropyrazole is readily converted to 5-amino-1-methyl-4-nitropyrazole; the production of 4-amino-1-methyl-5-nitropyrazole from 4-bromo-1-methyl-5-nitropyrazole requires the presence of a copper catalyst; under the same conditions in the amination of 4-bromo-1-methyl-3-nitropyrazole, 4-amino-1-methyl-3-nitro- and 1-methyl-3-nitropyrazoles are formed in a 2 : 3 ratio.
