Check Digit Verification of cas no

The CAS Registry Mumber 103645-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,6,4 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 103645-90:
(8*1)+(7*0)+(6*3)+(5*6)+(4*4)+(3*5)+(2*9)+(1*0)=105
105 % 10 = 5
So 103645-90-5 is a valid CAS Registry Number.
