Check Digit Verification of cas no

The CAS Registry Mumber 79942-41-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,9,4 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 79942-41:
(7*7)+(6*9)+(5*9)+(4*4)+(3*2)+(2*4)+(1*1)=179
179 % 10 = 9
So 79942-41-9 is a valid CAS Registry Number.

Base-catalysed Reaction of p- and o-Nitroanilines with Isocyanates and Isothiocyanates

Viswanathan, N.,Sidhaye, A. R.

, p. 611 - 613 (2007/10/02)

The reaction of p-nitroaniline with aryl isocyanates (2a-2d) in the presence of potassium carbonate leads to 4-nitrophenylamines (4a-4d).The reaction of p-nitroaniline with n-propyl isocyanate yields 4,4'-dinitrodiphenyl amine (10). o-Nitroaniline reacts with the isocyanates (2a and 2b) to yield 2-nitrodiphenyl amines (11a and 11b).The reaction of p-nitroaniline with phenyl isothiocyanate yields the guanidine (12) besides 4-nitrodiphenylamine (4a) and N,N'-diphenylthiourea.
