Check Digit Verification of cas no
The CAS Registry Mumber 39205-91-9 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, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 39205-91:
(7*3)+(6*9)+(5*2)+(4*0)+(3*5)+(2*9)+(1*1)=119
119 % 10 = 9
So 39205-91-9 is a valid CAS Registry Number.

Nitropyrazoles 5. Synthesis of substituted 3-nitropyrazoles from 3-amino-4-cyanopyrazole
Vinogradov, V. M.,Cherkasova, T. I.,Dalinger, I. L.,Shevelev, S. A.
, p. 1552 - 1554 (2007/10/02)
A preparative method of synthesis of 3-nitro-4-cyanopyrazole (1) from the available 3-amino-4-cyanopyrazole was developed.Chemical conversions of 1 were studied, and 3-nitro-4-R-pyrazoles (R = CO2H, CONH2, NHCO2Me, NH2, Br, NO2), as well as 3,5-dinitro-4-methoxycarbonylaminopyrazole were obtained starting from 1.
