Check Digit Verification of cas no

The CAS Registry Mumber 2111-54-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,1 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2111-54:
(6*2)+(5*1)+(4*1)+(3*1)+(2*5)+(1*4)=38
38 % 10 = 8
So 2111-54-8 is a valid CAS Registry Number.

Novel and efficient transformation of enamides into α-acyloxy ketones via an acyl intramolecular migration process

Zhou, Xiaoqiang,Ma, Haojie,Cao, Jinhui,Liu, Xingxing,Huang, Guosheng

supporting information, p. 10070 - 10073 (2016/11/06)

Hydrogen peroxide and anhydride mediated transformation of enamides to afford substituted α-acyloxy ketones is described. This transition-metal-free cascade reaction has a broad substrate scope and high efficiency. The acyl intramolecular migration procedure successfully achieved this acyloxylation process under mild conditions and increased the atom efficiency.

Palladium-catalyzed asymmetric hydrogenation of α-acyloxy-1- arylethanones

Chen, Jianzhong,Liu, Delong,Butt, Nicholas,Li, Chao,Fan, Dongyang,Liu, Yangang,Zhang, Wanbin

, p. 11632 - 11636 (2013/11/06)

First hand: The first example of a palladium-catalyzed asymmetric hydrogenation of α-acyloxy ketones (1) was accomplished to give the hydrogenated products 2 with by far the highest catalytic efficiency in up to quantitative conversions and excellent enantioselectivities. The hydrogenated products could serve as important intermediates for the preparation of many drug candidates. TFE=2,2,2-trifluoroethanol. Copyright
