Check Digit Verification of cas no

The CAS Registry Mumber 19989-70-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,8 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 19989-70:
(7*1)+(6*9)+(5*9)+(4*8)+(3*9)+(2*7)+(1*0)=179
179 % 10 = 9
So 19989-70-9 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 (2014/09/16)

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.
