5705-09-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5705-09-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,0 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5705-09:
(6*5)+(5*7)+(4*0)+(3*5)+(2*0)+(1*9)=89
89 % 10 = 9
So 5705-09-9 is a valid CAS Registry Number.

An efficient synthesis of: N -nitrosamines under solvent, metal and acid free conditions using tert -butyl nitrite

Chaudhary, Priyanka,Gupta, Surabhi,Muniyappan, Nalluchamy,Sabiah, Shahulhameed,Kandasamy, Jeyakumar

supporting information, p. 2323 - 2330 (2016/05/19)

Synthesis of various N-nitroso compounds from secondary amines is reported using tert-butyl nitrite (TBN) under solvent free conditions. Broad substrate scope, metal and acid free conditions, easy isolation procedure and excellent yields are few important features of this methodology. The acid labile protecting groups such as tert-butyldimethylsilyl (TBDMS) and tert-butyloxycarbonyl (Boc) as well as sensitive functional groups such as phenols, olefins and alkynes are found to be stable under the standard reaction conditions. Besides N-nitrosation, TBN is also found to be an efficient reagent in few other transformations including aryl hydrazines to aryl azides and primary amides to carboxylic acids under mild conditions.
