75700-33-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75700-33-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,7,0 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 75700-33:
(7*7)+(6*5)+(5*7)+(4*0)+(3*0)+(2*3)+(1*3)=123
123 % 10 = 3
So 75700-33-3 is a valid CAS Registry Number.

The Conversion of Secondary into Tertiary Amides Using Benzotriazole Methodology
Katritzky, Alan R.,Yao, Guowei,Lan, Xiangfu,Zhao, Xiaohong
, p. 2086 - 2093 (2007/10/02)
N-Alkyl-N-amides, easily prepared from benzotriazole, an aldehyde, and a secondary amide, react readily with organozinc reagents to give tertiary amides in moderate to good yields.They are also reduced by LiAlH4 to afford tertiary amines.
