Check Digit Verification of cas no

The CAS Registry Mumber 200353-84-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,3,5 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 200353-84:
(8*2)+(7*0)+(6*0)+(5*3)+(4*5)+(3*3)+(2*8)+(1*4)=80
80 % 10 = 0
So 200353-84-0 is a valid CAS Registry Number.

Synthesis of α-acetoxy and formyloxy ketones by thallium(III) promoted α-oxidation

Lee,Jin,Choi

, p. 956 - 957 (2007/10/03)

Treatment of ketones with thallium(III) triflate in amide solvents at 60°C for 30 min followed by addition of small amounts of H2O cleanly provided the corresponding α-acyloxy ketones.

A facile synthesis of secondary α-alkoxy or α-acetoxy aromatic ketones

Lee, Jong Chan,Hong, Taiyoung

, p. 4085 - 4090 (2007/10/03)

The treatment of HNIB with aromatic ketones and subsequent solvolysis using alcohol or acetic acid in one-pot system makes it possible to give corresponding secondary α-alkoxy or α-acetoxy ketones in high yields.
