Check Digit Verification of cas no

The CAS Registry Mumber 1092835-52-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,2,8,3 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1092835-52:
(9*1)+(8*0)+(7*9)+(6*2)+(5*8)+(4*3)+(3*5)+(2*5)+(1*2)=163
163 % 10 = 3
So 1092835-52-3 is a valid CAS Registry Number.

Synthesis of 4-arylcoumarins via Cu-catalyzed hydroarylation with arylboronic acids

Yamamoto, Yoshihiko,Kirai, Naohiro

, p. 5513 - 5516 (2008)

(Chemical Equation Presented) In the presence of 2-4 mol % of CuOAc, methyl phenylpropiolates having a MOM-protected hydroxy group at the ortho position underwent hydroarylation with various arylboronic acids in MeOH at ambient temperature, resulting in the formation of 4-arylcoumarins in high yields after the acidic workup. This method was effectively used for the synthesis of biologically active natural and artificial compounds.
