Check Digit Verification of cas no

The CAS Registry Mumber 66657-87-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,6,5 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 66657-87:
(7*6)+(6*6)+(5*6)+(4*5)+(3*7)+(2*8)+(1*7)=172
172 % 10 = 2
So 66657-87-2 is a valid CAS Registry Number.

Photochemical studies on aromatic γ,δ-epoxy ketones: Efficient synthesis of benzocyclobutanones and indanones

Shao, Yutian,Yang, Chao,Gui, Weijun,Liu, Yang,Xia, Wujiong

, p. 3560 - 3562 (2012/06/04)

Irradiation of terminal aromatic γ,δ-epoxy ketones with a 450 W UV lamp led to Norrish type II cyclization/semi-pinacol rearrangement cascade reaction which formed the benzocyclobutanones containing a full-carbon quaternary center, whereas irradiation of substituted aromatic γ,δ-epoxy ketones led to the indanones through a photochemical epoxy rearrangement and 1,5-biradicals cyclization tandem reaction.
