The CAS Registry Mumber 219533-80-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,5,3 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 219533-80:
(8*2)+(7*1)+(6*9)+(5*5)+(4*3)+(3*3)+(2*8)+(1*0)=139
139 % 10 = 9
So 219533-80-9 is a valid CAS Registry Number.

Novel photochemical addition of aromatic aldehydes to ketene dithioacetal S,S-dioxides and its application to organic synthesis

Ogura, Katsuyuki,Arai, Takayuki,Kayano, Akio,Akazome, Motohiro

, p. 9051 - 9054 (2007/10/03)

On irradiation (>290 nm) in the absence or presence of benzophenone, various aromatic aldehydes add to ketene dithioacetal S,S-dioxides to give the corresponding 1:1 adducts, which were shown to be synthetic precursors of indanone derivatives.
