Check Digit Verification of cas no
The CAS Registry Mumber 127445-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,4,4 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 127445-91:
(8*1)+(7*2)+(6*7)+(5*4)+(4*4)+(3*5)+(2*9)+(1*1)=134
134 % 10 = 4
So 127445-91-4 is a valid CAS Registry Number.

Preparation of Donor-Acceptor-Substituted Vinylcyclobutanes
Gruseck, Ursula,Heuschmann, Manfred
, p. 1905 - 1909 (2007/10/02)
2-Methylen-1,3-dioxolane (1) and the methyl acrylates or crotonates 2 form cycloadducts 3 which are reduced to give alcohols 6.Oxidation of these alcohols at low temperatures leads to unstable aldehydes 7, which either rearrange to dihydropyrans 5 or react with Wittig(-Horner) reagents to afford donor-acceptor-substituted vinylcyclobutanes 8.The cis-vinylcyclobutane 8g is prepared by cycloaddition of dioxolane 1 and methyl (2E,4Z)-hexadienoate (9).The configurations and preferred conformations of the vinylcyclobutanes 8 have unequivocally been assigned on the basis of 13C- and 1H-NMR spectra.
