Check Digit Verification of cas no

The CAS Registry Mumber 1403239-54-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,3,2,3 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1403239-54:
(9*1)+(8*4)+(7*0)+(6*3)+(5*2)+(4*3)+(3*9)+(2*5)+(1*4)=122
122 % 10 = 2
So 1403239-54-2 is a valid CAS Registry Number.

, p. 3830 - 3839 (2012/09/25)

Hyperbranched poly(ether sulfone)s were prepared by the self-polycondensation of the novel AB2 monomer, 4-(3,5- hydroxyphenoxy)-4'-fluorodiphenylsulfone. The high-molecular-weight polymers were isolated in good yields. The degree of branching (
