198905-40-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 198905-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,9,0 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 198905-40:
(8*1)+(7*9)+(6*8)+(5*9)+(4*0)+(3*5)+(2*4)+(1*0)=187
187 % 10 = 7
So 198905-40-7 is a valid CAS Registry Number.

Polymer supported bases in combinatorial chemistry: Synthesis of aryl ethers from phenols and alkyl halides and aryl halides

Xu, Wei,Mohan, Raju,Morrissey, Michael M.

, p. 7337 - 7340 (1997)

Polymer supported 1,5,7-triazabicyclo[4.4.0]dec-5-ene (PTBD) was used as a base and a reagent scavenger for rapid synthesis of aryl ethers from phenols and alkyl or aryl halides. This method provides a simple reaction operation, and generally high purity of reaction product in good yield.
