Check Digit Verification of cas no

The CAS Registry Mumber 1006376-62-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,6,3,7 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1006376-62:
(9*1)+(8*0)+(7*0)+(6*6)+(5*3)+(4*7)+(3*6)+(2*6)+(1*2)=120
120 % 10 = 0
So 1006376-62-0 is a valid CAS Registry Number.
