Check Digit Verification of cas no

The CAS Registry Mumber 140401-51-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,4,0 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 140401-51:
(8*1)+(7*4)+(6*0)+(5*4)+(4*0)+(3*1)+(2*5)+(1*1)=70
70 % 10 = 0
So 140401-51-0 is a valid CAS Registry Number.

Photochemistry of α-bis(methoxyimino)alkanes

Stunnenberg, Frank,Cerfontain, Hans

, p. 79 - 87 (2007/10/02)

The photochemistry of the α-bis(methoxyimino)alkanes 1-5 and the, structurally related, conjugated dihydro(methoxyimino)isoxazoles 6 and 7 was studied.Triplet-photosensitized irradiation of 1-7 leads only to stepwise E-Z isomerization.Photostationary-state (pss) ratios for 1, 6 and 7 are reported for the various applied triplet sensitizers.Direct irradiation with 254 nm leads to both E-Z isomerization (which is the dominant reaction) and formation of products resulting from initial N-O homolysis of the excited singlet ??* state.Mechanisms for the formation ofthe various products are proposed and the relative importance of the various steps is indicated and discussed.For the α-bis(methoxyimino)alkanes 1 and 3, only the (E,Z)-isomer undergoes N-O homolysis.With the (methoxyimino)isoxazolines 6 and 7, only the exocyclic N-O bond exhibits homolysis and not the strained endocyclic bond.
