170233-12-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 170233-12-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,2,3 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 170233-12:
(8*1)+(7*7)+(6*0)+(5*2)+(4*3)+(3*3)+(2*1)+(1*2)=92
92 % 10 = 2
So 170233-12-2 is a valid CAS Registry Number.

A facile one-pot transformation of carboxylic acids to amides
Lee,Cho,Lee,Cho
, p. 2877 - 2881 (2007/10/02)
Carboxylic acids, converted in situ into carboxylic-(p-nitrobenzene)sulfonic anhydrides using p-nitrobenzenesulfonyl chloride, Et3N, and DMAP in CH3CN, react with primary or secondary amines, to give amides in high yields.
