Check Digit Verification of cas no

The CAS Registry Mumber 517877-22-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,7,8,7 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 517877-22:
(8*5)+(7*1)+(6*7)+(5*8)+(4*7)+(3*7)+(2*2)+(1*2)=184
184 % 10 = 4
So 517877-22-4 is a valid CAS Registry Number.

Preparation, structure, and reaction of a sterically encumbered 1-phosphaallene containing a cyclopropylidene moiety

Ito, Shigekazu,Kimura, Shigeo,Yoshifuji, Masaaki

, p. 1111 - 1114 (2003)

(Matrix presented) Sterically protected (Z)-1-(2,4,6-tri-tert-butylphenyl)-2,5-dibromo-1-phosphapent-1-ene was allowed to react with potassium tert-butoxide to afford a cyclopropylidenephosphaethene, which was characterized spectroscopically and by X-ray
