Check Digit Verification of cas no

The CAS Registry Mumber 20849-53-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,4 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20849-53:
(7*2)+(6*0)+(5*8)+(4*4)+(3*9)+(2*5)+(1*3)=110
110 % 10 = 0
So 20849-53-0 is a valid CAS Registry Number.

Photochemical radical cyclization of γ,δ-unsaturated ketone oximes to 3,4-dihydro-2H-pyrroles

Kitamura, Mitsuru,Mori, Yutaka,Narasaka, Koichi

, p. 2373 - 2376 (2005)

3,4-Dihydro-2H-pyrroles are synthesized from γ, δ-unsaturated oximes by photochemical radical cyclization with 1,5-dimethoxynaphthalene (DMN) as the sensitizer. The cyclization of alkyl ketone O-acetyloximes proceeds via photosensitized electron transfer
