Check Digit Verification of cas no

The CAS Registry Mumber 81719-67-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,1 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81719-67:
(7*8)+(6*1)+(5*7)+(4*1)+(3*9)+(2*6)+(1*7)=147
147 % 10 = 7
So 81719-67-7 is a valid CAS Registry Number.

SELECTIVE SYNTHESES OF DENDROLASIN AND SESQUIROSEFURAN BY THE COUPLING OF 3-FURYLMETHYLMAGNESIUM BROMIDE WITH GERANYL DIETHYL PHOSPHATE

Araki, Shuki,Butsugan, Yasuo

, p. 177 - 178 (1982)

Coupling reaction of 3-furylmethylmagnesium bromide with geranyl diethyl phosphate in the presence and the absence of copper(I) iodide affords dendrolasin and sesquirosefuran, respectively, in ca. 80 percent selectivity

REGIO-CONTROLLED PRENYLATION AND GERANYLATION OF 3-FURYLMETHYLMAGNESIUM BROMIDE. SELECTIVE SYNTHESES OF 3-SUBSTITUTED FURANOID AND 2-SUBSTITUTED 3-METHYLFURANOID TERPENES.

Araki,Butsugan

, p. 1446 - 1449 (2007/10/02)

Coupling reactions of 3-furylmethylmagnesium bromide with prenyl and geranyl diethyl phosphates gave 2-substituted 3-methylfurans, rosefuran and sesquirosefuran, as the main products. When the reactions were carried out in the presence of a catalytic amount of copper(I) iodide, normal coupling occurred and 3-substituted furans, perillene and dendrolasin, were formed in good yields. The related naturally occurring 3-substituted thiophene, 3-(4-methyl-3-pentenyl)thiophene, was also synthesized from 3-thienylmethylmagnesium bromide and prenyl diethy phosphate.
