Check Digit Verification of cas no

The CAS Registry Mumber 102735-85-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,7,3 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 102735-85:
(8*1)+(7*0)+(6*2)+(5*7)+(4*3)+(3*5)+(2*8)+(1*5)=103
103 % 10 = 3
So 102735-85-3 is a valid CAS Registry Number.
