Check Digit Verification of cas no

The CAS Registry Mumber 1995-49-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,9 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1995-49:
(6*1)+(5*9)+(4*9)+(3*5)+(2*4)+(1*9)=119
119 % 10 = 9
So 1995-49-9 is a valid CAS Registry Number.

One-pot synthesis of 3,5-disubstituted and polysubstituted phenols from acyclic precursors

Qian, Jinlong,Yi, Wenbin,Huang, Xin,Miao, Yongbo,Zhang, Junkai,Cai, Chun,Zhang, Wei

supporting information, p. 1090 - 1093 (2015/03/14)

A new strategy for the synthesis of 3,5-disubstituted phenols is established through one-pot Robinson annulation of α,β-unsaturated ketones with α-fluoro-β-ketoesters followed by in situ dehydrofluorination and tautomerization. This method has been extended to the synthesis of polysubstituted phenols and applied in the preparation of biologically active compounds.
