Check Digit Verification of cas no

The CAS Registry Mumber 127258-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,2,5 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 127258-01:
(8*1)+(7*2)+(6*7)+(5*2)+(4*5)+(3*8)+(2*0)+(1*1)=119
119 % 10 = 9
So 127258-01-9 is a valid CAS Registry Number.

Photooxygenation of 1-Alkyl-2,3-diarylcyclopropanes via Photoinduced Electron Transfer: Stereoselective Formation of 4-Alkyl-3,5-diaryl-1,2-dioxolanes and Their Conversion to 1,3-Diols

Ichinose, Nobuyuki,Mizuno, Kazuhiko,Tamai, Toshiyuki,Otsuji, Yoshio

, p. 4079 - 4083 (2007/10/02)

The 9,10-dicyanoanthracene-sensitized photooxygenation of 1-alkyl-2,3-diarylcyclopropanes in CH3CN afforded c-4-alkyl-r-3,t-5-diaryl-1,2-dioxolanes in excellent yields with high stereoselectivity, which upon hydrogenolysis on Pd-charcoal gave quantitatively the corresponding 1,2-threo-2,3-erythro-2-alkyl-1,3-diaryl-1,3-diols.
