Check Digit Verification of cas no

The CAS Registry Mumber 1390641-50-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,0,6,4 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1390641-50:
(9*1)+(8*3)+(7*9)+(6*0)+(5*6)+(4*4)+(3*1)+(2*5)+(1*0)=155
155 % 10 = 5
So 1390641-50-5 is a valid CAS Registry Number.
