Check Digit Verification of cas no

The CAS Registry Mumber 77143-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,4 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77143-20:
(7*7)+(6*7)+(5*1)+(4*4)+(3*3)+(2*2)+(1*0)=125
125 % 10 = 5
So 77143-20-5 is a valid CAS Registry Number.

Photochemishe Reactionen 110. Mitteilung Zur Photochemie γ,δ-Methano-α-enone

Ishii, Keitaro,Wolf, Hans Richerd,Jeger, Oskar

, p. 1520 - 1537 (1980)

Direct excitation (λ=254 or >/=347 nm) converts the γ,δ-methano-α-enone (E)-10 into the isomeric ether 23 and the isomeric diene-ketone 24.Furthermore, on 1?,?*-excitation (λ=254 nm) (E)-10 undergoes an 1,3-homosigmatropic rearrangem
