Check Digit Verification of cas no
The CAS Registry Mumber 5821-59-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,2 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5821-59:
(6*5)+(5*8)+(4*2)+(3*1)+(2*5)+(1*9)=100
100 % 10 = 0
So 5821-59-0 is a valid CAS Registry Number.

A New method of synthesizing phenalen-1-one: Reduction of 3-hydroxyphenalen-1-one using nabh4 and lanthanoid chlorides

Phenalen-1-one was obtained in considerable yield by reducing 3-hydroxyphenalen-1-one. Most of known preparation methods are not very practical, either because their yields are very poor or because their processes have many steps. This regioselective 1,2-reduction proceeded by the action of NaBH4 and various cations of rare-earth elements and metals. The yields of phenalen-1-one were examined as a function of typical lanthanoids, molar ratios of lanthanoid ions to 3-acetoxy-phenalen-1-one, and differing methods of protecting the hydroxyl group. Lanthanum chloride (LaCl3) gave the greatest yield (45.3%) of phenalen-1-one at molar ratios higher than a third, probably because La3+ ion is a hard acid and coordinates easily to a hard solvent such as methanol. Further, it has the largest ionic radius among all lanthanoid ions. Copyright Taylor & Francis Group, LLC.
