Check Digit Verification of cas no

The CAS Registry Mumber 85604-67-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,6,0 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 85604-67:
(7*8)+(6*5)+(5*6)+(4*0)+(3*4)+(2*6)+(1*7)=147
147 % 10 = 7
So 85604-67-7 is a valid CAS Registry Number.

Ruthenium(III) acetylacetonate [Ru(acac)3] - An efficient chemoselective catalyst for the tetrahydropyranylation (THP) of alcohols and phenols under solvent-free conditions

Varala, Ravi,Adapa, Srinivas R.

, p. 1174 - 1179 (2007/10/03)

A catalytic amount of ruthenium(III) acetylacetonate (2 mol%) [Ru(acac)3] enables solvent-free tetrahydropyranylation of different types of alcohols and phenols at ambient temperature in moderate to excellent yields. Notably, selective monoprotection of diols can be achieved chemoselectively. Furthermore, the catalyst could be recovered and reused if necessary.

Photocyclisations de cetoacetals aromatiques en vue d'une approche synthetique de la crombenine

Cottet, Francoise,Cottier, Louis,Descotes, Gerard

, p. 1251 - 1257 (2007/10/02)

Combenin 1 is a spiropeltogynoid compound with a spiroacetal moiety.A similar structure was synthesized starting from and orthocarbonylphenoxyisochroman by a Norrish type II photocyclisation.With an isochroman compound, the aromatic ring induces benzyl ra
