Check Digit Verification of cas no

The CAS Registry Mumber 54978-05-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,9,7 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 54978-05:
(7*5)+(6*4)+(5*9)+(4*7)+(3*8)+(2*0)+(1*5)=161
161 % 10 = 1
So 54978-05-1 is a valid CAS Registry Number.

Nitrosation of the N-Alkyl-O-acylhydroxylamines. A New Deamination Method.

White, Emil H.,Ribi, Max,Cho, Lee K.,Egger, Notker,Dzadzic, Petar M.,Todd, Michael J.

, p. 4866 - 4871 (2007/10/02)

The nitrosation of N-alkyl-O-acylhydroxylamines leads to immediate decomposition at dry ice temperatures; the corresponding ester and nitrous oxide are formed.An 18O study has shown that the nitroso-O-acylhydroxylamines fragment directly rather than undergo a rearrangement reaction (as observed with the nitrosoamides).The product yields are respectable, especially at low tempreatures, and the method has promise for the generation of high energy carbonium ions.
