Check Digit Verification of cas no

The CAS Registry Mumber 809234-34-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,9,2,3 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 809234-34:
(8*8)+(7*0)+(6*9)+(5*2)+(4*3)+(3*4)+(2*3)+(1*4)=162
162 % 10 = 2
So 809234-34-2 is a valid CAS Registry Number.

ZrCl4-catalyzed Pechmann reaction: Synthesis of coumarins under solvent-free conditions

Smitha,Reddy, Ch. Sanjeeva

, p. 3997 - 4003 (2004)

Zirconium (IV) chloride is used as an efficient catalyst in the Pechmann condensation reaction of phenols with β-keto esters leading to the formation of coumarin derivatives in good yields under solvent-free conditions.
