Check Digit Verification of cas no

The CAS Registry Mumber 141519-92-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,5,1 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 141519-92:
(8*1)+(7*4)+(6*1)+(5*5)+(4*1)+(3*9)+(2*9)+(1*2)=118
118 % 10 = 8
So 141519-92-8 is a valid CAS Registry Number.

Vic-tricarbonyl compounds: Synthesis of (±)-9-epi-wailupemycin A

Seitz, Tobias,Harms, Klaus,Koert, Ulrich

, p. 381 - 386 (2014)

A synthesis of the 9-epimer of the marine natural product wailupemycin A is reported. The key reaction sequence consists of a diastereoselective enamine addition to a tricarbonyl monohydrate, the formation of an enol silyl acetal, and finally the stereoco

Facile synthesis of 1,2,3-tricarbonyls from 1,3-dicarbonyls mediated by cerium(IV) ammonium nitrate

Sivan, Akhil,Deepthi, Ani

supporting information, p. 1890 - 1893 (2014/03/21)

A mild and efficient protocol for the synthesis of vicinal tricarbonyl compounds from β-dicarbonyls in a single step using cerium(IV) ammonium nitrate as a catalytic oxidant is described. Ease of execution, wide substrate scope and the suitability for the synthesis of commercially important compounds like ninhydrin, alloxan and oxoline make this reaction particularly noteworthy.
