7216-40-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7216-40-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,1 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7216-40:
(6*7)+(5*2)+(4*1)+(3*6)+(2*4)+(1*0)=82
82 % 10 = 2
So 7216-40-2 is a valid CAS Registry Number.

Chemoselective N-oxidation of picolinaldehydes with dimethyldioxirane

Dyker, Gerald,Hoelzer, Bettina

, p. 12557 - 12562 (2007/10/03)

The N-oxidation of picolinaldehydes with dimethyldioxirane proceeds with remarkable selectivity. Especially the N-oxides of 3- and of 4- picolinaldehyde are isolated in high yields. The aldehyde-hydrate 3- dihydoxymethylpyridin-N-oxide was fully characterized.
