Check Digit Verification of cas no

The CAS Registry Mumber 1381939-50-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,1,9,3 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1381939-50:
(9*1)+(8*3)+(7*8)+(6*1)+(5*9)+(4*3)+(3*9)+(2*5)+(1*0)=189
189 % 10 = 9
So 1381939-50-9 is a valid CAS Registry Number.
