109000-78-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109000-78-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,0 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109000-78:
(8*1)+(7*0)+(6*9)+(5*0)+(4*0)+(3*0)+(2*7)+(1*8)=84
84 % 10 = 4
So 109000-78-4 is a valid CAS Registry Number.

META PHOTOCYCLOADDITION OF TRANS-1,2-DICHLOROETHYLENE TO BENZENOID COMPOUNDS: MECHANISTIC CONSIDERATIONS AND PHOTO AND THERMAL LABILITIES OF THE ADDUCTS

Cornelisse, Jan,Gilbert, Andrew,Rodwell, Paul W.

, p. 5003 - 5006 (2007/10/02)

The observed specificity of meta photocycloaddition of trans 1,2-dichloroethylene to benzenoid compounds is deduced to arise from a chlorine atom induced asymmetric distortion of the reaction intermediate: thermal and photochemical isomerisations of the adducts occur by an ethenylcyclopropane-cyclopentene rearrangement and/or 1,3- and 1,5-chlorine shifts.
