Check Digit Verification of cas no

The CAS Registry Mumber 40924-04-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,2 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 40924-04:
(7*4)+(6*0)+(5*9)+(4*2)+(3*4)+(2*0)+(1*4)=97
97 % 10 = 7
So 40924-04-7 is a valid CAS Registry Number.

Aryloxy Radicals from Diaryloxydiazirines: α-Cleavage of Diaryloxycarbenes or Excited Diazirines?

Fede, Jean-Marie,Jockusch, Steffen,Lin, Nan,Moss, Robert A.,Turro, Nicholas J.

, p. 5027 - 5030 (2003)

(Equation presented) The synthesis of diaryloxydiazirines, precursors to diaryloxycarbenes, is described. Thermolyses of the diazirines afford anticipated carbene products, but photolyses afford both carbenes and aryloxy radicals by α-scission. UV spectra of the carbenes and radicals are observed.
