Check Digit Verification of cas no

The CAS Registry Mumber 1228180-66-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,1,8 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1228180-66:
(9*1)+(8*2)+(7*2)+(6*8)+(5*1)+(4*8)+(3*0)+(2*6)+(1*6)=142
142 % 10 = 2
So 1228180-66-2 is a valid CAS Registry Number.

Oxidative Coupling of 1,3-Dicarbonyl Compounds by Cerium(IV) Ammonium Nitrate

Song, Jianan,Zhang, Hao,Chen, Xianjun,Li, Xinsheng,Xu, Dongcheng

experimental part, p. 1847 - 1855 (2010/07/02)

A fast, mild, and highly efficient method for the intermolecular coupling of 1,3-dicarbonyl compounds using cerium ammonium nitrate in CH 3CN/CH3OH/H2O has been described. The procedure provided a convenient method for the synthesis of 1,4-diketone derivatives with excellent yields (up to 96%) and powerful evidence for the oxidation mechanism mediated by cerium ammonium nitrate.
