Check Digit Verification of cas no
The CAS Registry Mumber 151588-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,5,8 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 151588-03:
(8*1)+(7*5)+(6*1)+(5*5)+(4*8)+(3*8)+(2*0)+(1*3)=133
133 % 10 = 3
So 151588-03-3 is a valid CAS Registry Number.

Nitropyrazoles 4. N-Amination under control of the pH of the medium
Vinogradov, V. M.,Dalinger, I. L.,Gulevskaya, V. I.,Shevelev, S. A.
, p. 1369 - 1371 (1993)
A preparative method of N-amination of pyrazoles bearing nitro groups and other electron withdrawing substituents in the pyrazole ring with hydroxylamine-O-sulfonic acid involving control of the pH of the medium has been elaborated.A series of previously unknown pyrazoles has been prepared.Basicities (pKBH+) of 1-aminopyrazole and 1-amino-4-nitropyrazole have been measured and differences between the basicities of the C- and N-amino groups for the pyrazole series have been revealed. - Key words: nitropyrazoles, N-aminopyrazoles, N-amination.
