Check Digit Verification of cas no
The CAS Registry Mumber 1205537-80-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,5,5,3 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1205537-80:
(9*1)+(8*2)+(7*0)+(6*5)+(5*5)+(4*3)+(3*7)+(2*8)+(1*0)=129
129 % 10 = 9
So 1205537-80-9 is a valid CAS Registry Number.

Synthesis and structural aspects of N-triflylphosphoramides and their calcium salts'highly acidic and effective Bronsted acids
Rueping, Magnus,Nachtsheim, Boris J.,Koenigs, Rene M.,Ieawsuwan, Winai
experimental part, p. 13116 - 13126 (2011/02/24)
Recently, 1,1′-bi-2-naphthol (BINOL)-based N-triflylphosphoramides emerged as a new class of potent Bronsted acid catalysts. In this paper we describe the efficient synthesis of various BINOL-based N- triflylphosphoramides and their calcium salts. Furthermore, X-ray crystal structure analysis combined with energy-dispersive X-ray spectroscopy (EDX) measurements confirmed that the synthesised chiral N-triflylphosphoramides are highly acidic metal-free catalysts. Freedom! The synthesis and structure determination of various 1,1′-bi-2-naphthol (BINOL)-based N-triflylphosphoramides and their corresponding calcium salts is presented. A simple acidic treatment of the calcium salts provides the metal-free Bronsted acids (see scheme; Tf=trifluoromethanesulfonyl).
