Check Digit Verification of cas no

The CAS Registry Mumber 1443992-32-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,9,9 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1443992-32:
(9*1)+(8*4)+(7*4)+(6*3)+(5*9)+(4*9)+(3*2)+(2*3)+(1*2)=182
182 % 10 = 2
So 1443992-32-2 is a valid CAS Registry Number.

Regioselective synthesis of pyrano[3,2-c]coumarins via Cu(II)-catalyzed tandem reaction

Bagdi, Avik Kumar,Majee, Adinath,Hajra, Alakananda

, p. 3892 - 3895 (2013)

Efficient synthesis of pyrano[3,2-c]coumarins has been achieved via copper(II) triflate catalyzed tandem reaction of 4-hydroxycoumarin with α,β-unsaturated carbonyl compounds in high yields. The catalytic reaction proceeded very smoothly under solvent-fre
