Check Digit Verification of cas no

The CAS Registry Mumber 203454-64-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,4,5 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 203454-64:
(8*2)+(7*0)+(6*3)+(5*4)+(4*5)+(3*4)+(2*6)+(1*4)=102
102 % 10 = 2
So 203454-64-2 is a valid CAS Registry Number.
