67814-83-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 67814-83-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,8,1 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 67814-83:
(7*6)+(6*7)+(5*8)+(4*1)+(3*4)+(2*8)+(1*3)=159
159 % 10 = 9
So 67814-83-9 is a valid CAS Registry Number.

LANOSTANE TO CUCURBITANE TRANSFORMATIONS

Edwards, O. E.,Kolt, R. J.

, p. 595 - 612 (2007/10/02)

Transformation of 3,7,9,11-tetraoxygenated lanostane derivatives into 3,7,11-trioxygenated cucurbit-1(10)-enes and cucurbit-5(10)-enes has been achieved.Attempts to convert the latter in good yield into cucurbit-5-enes are documented.The steric and electronic factors influencing the course of dehydration, under Westphalen conditions, of 9α-hydroxylanostane derivatives are discussed.Unusual autooxidation and dehydrogenation promoted by rhodium trichloride and iron pentacarbonyl are described.

Tetracyclic triterpenes. VIII. The skeletal rearrangement of 3β-acetoxy-9α,11α-epoxy-5α-lanostan-7-one: 13- and 10-methyl group migration

Paryzek, Zdzislaw,Widra, Roman

, p. 1280 - 1286 (2007/10/02)

The boron trifluoride etherate catalyzed rearrangement of 3β-acetoxy-9α, 11α-epoxy-5α-lanostan-7-one (1) in acetic acid anhydride resulted in formation of 19(10->9β)abeo compounds 2 and 4 along with 18(13->12β)abeo compound 5, as the major product.These structures are supported by spectral data and chemical transfomations.The possible mechanism of the rearrangements is discussed.

PHOTOCHEMICAL REARRANGEMENTS OF 18-HYDROXYLATED LANOSTEROL DERIVATIVES

Habermehl, Gerhard G.,Kirsch, Juergen H.,Reibstein, Karl J.

, p. 183 - 189 (2007/10/02)

Several lanosterol derivatives with 18-hydroxyl group were subjected to the hypoiodite reaction.A new C-secosteroid was obtained as well as the desired 5-membered 18,20-epoxy compound.
