Check Digit Verification of cas no

The CAS Registry Mumber 1039643-72-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,9,6,4 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1039643-72:
(9*1)+(8*0)+(7*3)+(6*9)+(5*6)+(4*4)+(3*3)+(2*7)+(1*2)=155
155 % 10 = 5
So 1039643-72-5 is a valid CAS Registry Number.
