Check Digit Verification of cas no

The CAS Registry Mumber 208753-42-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,7,5 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 208753-42:
(8*2)+(7*0)+(6*8)+(5*7)+(4*5)+(3*3)+(2*4)+(1*2)=138
138 % 10 = 8
So 208753-42-8 is a valid CAS Registry Number.
