Check Digit Verification of cas no

The CAS Registry Mumber 140840-98-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,4 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 140840-98:
(8*1)+(7*4)+(6*0)+(5*8)+(4*4)+(3*0)+(2*9)+(1*8)=118
118 % 10 = 8
So 140840-98-8 is a valid CAS Registry Number.

Direct oxidative cyclization of 3-arylpropionic acids using PIFA or Oxone: synthesis of 3,4-dihydrocoumarins

Gu, Yonghong,Xue, Kun

, p. 192 - 196 (2010)

The direct oxidative cyclization of 3-arylpropionic acids using PIFA or Oxone is reported. In the presence of BF3·OEt2, the reaction of 3-arylpropionic acids with PIFA or Oxone proceeded smoothly at 30 °C to give 3,4-dihydrocoumarins
