Check Digit Verification of cas no

The CAS Registry Mumber 1620962-03-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,9,6 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1620962-03:
(9*1)+(8*6)+(7*2)+(6*0)+(5*9)+(4*6)+(3*2)+(2*0)+(1*3)=149
149 % 10 = 9
So 1620962-03-9 is a valid CAS Registry Number.
