Check Digit Verification of cas no

The CAS Registry Mumber 143731-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,3 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143731-90:
(8*1)+(7*4)+(6*3)+(5*7)+(4*3)+(3*1)+(2*9)+(1*0)=122
122 % 10 = 2
So 143731-90-2 is a valid CAS Registry Number.
