Check Digit Verification of cas no

The CAS Registry Mumber 1287795-51-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,7,7,9 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1287795-51:
(9*1)+(8*2)+(7*8)+(6*7)+(5*7)+(4*9)+(3*5)+(2*5)+(1*1)=220
220 % 10 = 0
So 1287795-51-0 is a valid CAS Registry Number.
