1169841-49-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1169841-49-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,9,8,4 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1169841-49:
(9*1)+(8*1)+(7*6)+(6*9)+(5*8)+(4*4)+(3*1)+(2*4)+(1*9)=189
189 % 10 = 9
So 1169841-49-9 is a valid CAS Registry Number.

scheme or table, p. 2059 - 2062 (2009/09/06)
Copper salt catalyzed imidation of tertiary amines by using sulfonyl azides as the nitrogen source was achieved with moderate to high yields. Formation of the carbon-nitrogen bond occurred chemoselectively with the use of a simple and inexpensive catalyst
