Check Digit Verification of cas no

The CAS Registry Mumber 1638640-19-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,8,6,4 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1638640-19:
(9*1)+(8*6)+(7*3)+(6*8)+(5*6)+(4*4)+(3*0)+(2*1)+(1*9)=183
183 % 10 = 3
So 1638640-19-3 is a valid CAS Registry Number.

Direct assembly of 3,4-difunctionalized benzofurans and polycyclic benzofurans by phenol dearomatization and palladium-catalyzed domino reaction

Han, Zhaomeng,Zhang, Liang,Li, Zhiming,Fan, Renhua

, p. 6805 - 6809 (2014/07/08)

A method to directly convert 2-alkynylphenols to 3,4-difunctionalized benzofurans and polycyclic benzofurans was developed. This protocol involves a hypervalent-iodine-mediated oxidative dearomatization to break the aromaticity of 2-alkynylphenols, and a
