General Description
NISTC2156710, also known as 2-butanol, is a chemical compound with the molecular formula C4H10O. It is a colorless liquid with a strong, sweet odor, and is commonly used as a solvent and in the production of various chemicals. 2-butanol is flammable and can be harmful if inhaled, ingested, or absorbed through the skin. It is also a respiratory and skin irritant and should be handled with care. In addition, 2-butanol is known to be toxic to aquatic organisms and should be disposed of properly to prevent environmental contamination. Overall, NISTC2156710 is a versatile chemical with various industrial applications, but proper safety precautions should be taken when handling and using it.
Check Digit Verification of cas no
The CAS Registry Mumber 2156-71-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,5 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2156-71:
(6*2)+(5*1)+(4*5)+(3*6)+(2*7)+(1*1)=70
70 % 10 = 0
So 2156-71-0 is a valid CAS Registry Number.

Structure-activity considerations in kinetics and mechanism of chlorine exchange between chloramine-T and secondary amines
Dannan,Hussain,Crooks,Dittert
, p. 657 - 660 (2007/10/02)
To study the mechanism of N-chlorination of secondary amines by chloramine-T, the kinetics of the reactions of some aromatic-substituted analogues of N-chlorobenzenesulfonamide with various secondary amines were determined. The importance of amine basicity and reactivity of the N-Cl bond of the N-chlorobenzenesulfonamide was also assessed. The results indicate that a mechanism involving the un-ionized species of both reactants (i.e., a molecular mechanism), rather than an ionic mechanism, is operating and that the reaction most likely proceeds via a six-membered-ring transition state that incorporates a water molecule.
