Check Digit Verification of cas no

The CAS Registry Mumber 63901-87-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,9,0 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 63901-87:
(7*6)+(6*3)+(5*9)+(4*0)+(3*1)+(2*8)+(1*7)=131
131 % 10 = 1
So 63901-87-1 is a valid CAS Registry Number.

CuBr2-promoted tetrahydrofuranylation of alcohols and 1,3-dione

Wang, Meng-Ke,Zhou, Zeng-Le,Tang, Ri-Yuan,Zhang, Xing-Guo,Deng, Chen-Liang

supporting information, p. 737 - 740 (2013/05/08)

A method for the CuBr2-promoted tetrahydrofuranylation of alcohols and 1,3-dione has been developed. A variety of different alcohols were efficiently converted into the corresponding 2-tetrahydrofuran ethers in the presence of CuBr2. It is noteworthy that this protocol also successfully converted 1,3-diphenyl-1,3-dione into the corresponding 2-tetrahydrofuran derivative in good yield. Georg Thieme Verlag Stuttgart - New York.

MIXED AROMATIC-ALIPHATIC ACETALS; THEIR PREPARATION, (1)H AND (13)C-NMR SPECTRA AND HYDROGENOLYSIS BY ETHEREAL SOLUTION OF CHLOROALANE

Dusek, Jiri,Sklenar, Vladimir,Jonas, Jaroslav

, p. 2912 - 2923 (2007/10/02)

The corresponding p-X-phenylisobutyl acetals of acetaldehyde (I), 2-(p-X-phenoxy)tetrahydropyrans (II), 2-(p-X-phenoxy)tetrahydrofurans (III), and cyclohexyl(p-X-phenyl)acetals of acetaldehyde (IV) were prepared by addition of p-X-substituted phenols to isobutyl vinyl ether, 2,3-dihydro-4H-pyran, 2,3-dihydrofuran, and cyclohexyl vinyl ether, respectively.The structures of acetals I-IV were confirmed by their (1)H and (13)C-NMR spectra.Diastereotopic protons of the methylene and geminal methyl groups are anisochronous in the (1)H-NMR spectra of acetals I. (13)C-NMR spectra of acetals IV demonstrate anisochronous behaviour of cyclohexane ring diastereotopic carbon atoms.The constants ?p+ for several groups calculated using (13)C-NMR spectra are: 1-isobutoxy-1-ethoxy- (-0.58), 2-tetrahydrofuryloxy- (-0.59), and 1-cyclohexyloxy-(1-ethoxy) (-0.57).Experimental relative rate constants of hydrogenolysis of acetals I and II by ethereal solution of chloroalane yield best correlations with ?p+ constants of the substituent X, providing the values ρ= -1.09 for compounds of the series I and II, respectively.The importance of these results for finding the rate determining step of the studied reaction is discussed.
