Check Digit Verification of cas no

The CAS Registry Mumber 860521-46-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,0,5,2 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 860521-46:
(8*8)+(7*6)+(6*0)+(5*5)+(4*2)+(3*1)+(2*4)+(1*6)=156
156 % 10 = 6
So 860521-46-6 is a valid CAS Registry Number.

Organocatalytic syntheses of benzoxazoles and benzothiazoles using aryl iodide and oxone via C-H functionalization and C-O/S bond formation

Alla, Santhosh Kumar,Sadhu, Pradeep,Punniyamurthy, Tharmalingam

, p. 7502 - 7511 (2014)

An organocatalytic protocol for the syntheses of 2-substituted benzoxazoles and benzothiazoles is described from alkyl-/arylanilides and alkyl-/arylthioanilides using 1-iodo-4-nitrobenzene as catalyst and oxone as an inexpensive and environmentally safe terminal oxidant at room temperature in air via oxidative C-H functionalization and C-O/S bond formation. The procedure is simple and general and provides an effective route for the construction of functionalized 2-alkyl-/arylbenzoxazoles and 2-alkyl-/arylbenzothiazoles with moderate to high yields. The synthetic and mechanistic aspects have been described.
